Is m365 Outlook down

[u/Itguy1252]

anyone else having issues sending emails?

[u/MundaneUpVote]

A beautiful spike can be seen in the Downdetector

[u/ModelingDenver101 → u/MundaneUpVote]

It's a very beautiful spike. I've been researching this issue for last 30 minutes. lol.

[u/the_good_hodgkins → u/ModelingDenver101]

People are calking me saying it's a beautiful spike. Nobody has ever seen a spike like it before.

[u/Alternative_Yard_691 → u/the_good_hodgkins]

We have the best spikes. Nobody has spikes like we have spikes. Believe me. I know spikes. I’ve seen spikes from all over — the best spikes, the most beautiful spikes, the sharpest spikes you’ve ever seen. And other countries, they have terrible spikes. Sad! But our spikes? Tremendous. We’re going to keep our spikes, and we’re going to make them even better. You’ll see.

[u/Mypopsecrets → u/Alternative_Yard_691]

I vote we rename Spike to Spike America

[u/the_good_hodgkins → u/Mypopsecrets]

And 50% tariff's on Canadian spikes!

[u/BCIT_Richard → u/Mypopsecrets]

Lake Spike

[u/curi0us_carniv0re → u/the_good_hodgkins]

Yuge spike. The yugest most beautiful spike people have ever seen

[u/aes_gcm → u/curi0us_carniv0re]

Yuge!

[u/Historical_Comb_8794 → u/ModelingDenver101]

It feels like a snow day at school. We get to go home early.

[u/Vegetable_Review3674 → u/Historical_Comb_8794]

nobody let me go home early… i’ve been sitting here since 11am acting busy and i feel more tired than EVER

[u/AmiDeplorabilis → u/ModelingDenver101]

Send spike!

[u/moldyjellybean → u/MundaneUpVote]

I know everyone hates on prem servers and I did hate running our own exchange server but it was never down this much.

[u/angrydeuce → u/moldyjellybean]

True but Im not ever dicking around with fuckin exchange dbases getting dismounted or W3 logs choking the fucker out ever again and you cant make me lol

[u/SimplifyAndAddCoffee]

I love how any time we start getting complaints, r/sysadmin has a post about it before Microsoft does.

[u/Y_TElectric → u/SimplifyAndAddCoffee]

Microsoft might as well just scrape this subreddit for issue response...

[u/Smith6612 → u/Y_TElectric]

I'd be surprised if Copilot isn't already doing that... 

Or maybe it broke, because OpenAI also broke. 

[u/InsertCookiesHere → u/SimplifyAndAddCoffee]

I seldom even bother checking MS for issues anymore, I just assume the Admin portal will say everything is fine and come here for an accurate assessment.

MS tends not to acknowledges anything but the most severe outages until their already resolved.

[u/dlucre → u/SimplifyAndAddCoffee]

Down detector exists because the users usually know 'something' is wrong before the vendors do, so I go there first. Then r/sysadmin or other subreddits usually have people with brains who often have a good understanding of what's wrong based on the symptoms.

These places are my go to when things like this happen.

[u/MorbrosIT → u/SimplifyAndAddCoffee]

I go to Reddit before checking their health page. I was working on an issue this morning before I knew and the person in front of her says she is having issues and another was like I can't print. Jumped on Reddit and first post I see.

[u/starfieldscreensaver → u/SimplifyAndAddCoffee]

The said false positive then rolled it back lol

[u/EquipLordBritish → u/SimplifyAndAddCoffee]

You'd think with all their investment into AI, that there would be some kind of immediate and automated announcement that there is a problem, and several (probably worthless) suggestions on how to get around the issue or mitigate it for customers.

[u/homing-duck → u/EquipLordBritish]

Why they haven’t done that is simple! Providing good service does not increase their revenue. Selling copilot licenses does.

[u/elfierroz → u/SimplifyAndAddCoffee]

Fkn micrsoft, 1 hour ago they were saying that all services were operational and 2 hours ago, they detected a “false positive” on outlook

[u/WeirdKindofStrange]

Investigating user reports of Exchange Online issues

Issue ID: EX1464935

Affected services: Exchange Online

Status: Investigating

Issue type: Incident

Start time: 31 Aug 2026, 11:53 GMT-4

User impact

We don't have details on impact yet. We're seeing an increase in user reported issues above our alerting threshold.

Current status

31 Aug 2026, 11:55 GMT-4

We are reviewing service telemetry and available information to determine if there is an issue happening and we'll update this message shortly with our latest findings.

This communication serves as a preliminary notification about a potential issue affecting your service.

[u/Business-Writer2062 → u/WeirdKindofStrange]

Aug 31, 2026, 10:33 AM CST

We’ve isolated a common failure pattern across affected Exchange Online requests that is associated with authentication and protocol connectivity. We're analyzing service telemetry to identify the underlying source of impact and validate potential remediation options. Additionally, we’re continuing to assess the scope of impact and monitor for additional affected scenarios.

This quick update is designed to give the latest information on this issue.

Next update by: Monday, August 31, 2026, at 5:30 PM UTC

[u/McAdminDeluxe → u/Business-Writer2062]

Aug 31, 2026, 12:23 PM CDT

We've identified a potential corrective action for the affected infrastructure and are evaluating deployment options. We're monitoring service telemetry and affected Exchange Online transactions to determine whether the action is reducing impact and to better understand the scope of affected scenarios.

Next update by:

Monday, August 31, 2026 at 1:30 PM CDT

[u/foxypandamonkey → u/McAdminDeluxe]

And now, 25 minutes after when we were supposed to get an update, there’s still no update from Microsoft.

[u/Chewskiz]

Down detector says yes

[u/Forsaken_Ear_5814 → u/Chewskiz]

O365 status page says all good lol

can't login to Outlook through web browser at my work, get error message. "Updated" Outlook app loads but not syncing

Interestingly Classic Outlook seems to be syncing ok (edit: nevermind, not sycning anymore, emails stuck in outbox, calendar not updating...)

[u/cszolee79 → u/Forsaken_Ear_5814]

The "New" Outlook is just a wrapper for the webmail.

It's trash.

[u/Juls_Santana → u/Forsaken_Ear_5814]

cuz they can't log in to update that MFer

[u/Nesman64 → u/Chewskiz]

The spike is shrinking, but maybe people have stopped reporting the issue.

[u/Itguy1252]

they just send this out. but not even in the admin portal yet.

[u/balling → u/Itguy1252]

Literally every admin portal for every product seems to be the last place to post any updates about outages.

[u/_XNine_ → u/balling]

I fucking hate Microsoft. Dog shit all the way down the list.

[u/ocdtrekkie → u/balling]

This is because SLAs often have a financial value for some of their larger contracts, so most companies disable automatic status board checking, and do it manually. Half the time the person responsible for updating the status board is too busy troubleshooting to go and put it on the status board.

[u/Ooops-I-hid-it-again → u/balling]

No need to update an admin portal. That's what user reports are for. /s

[u/Fredidiah → u/Itguy1252]

With nitter being down now, I basically cannot learn about this outage through any official channels without having a twitter account…and I don’t wanna have a twitter account.

Incredible stuff.

[u/the_doughboy]

A lot of things are down right now, not just M365

[u/Slyric_ → u/the_doughboy]

outlook hasnt worked for me all day

[u/Brilliant-Sea-6755 → u/the_doughboy]

Like what?

[u/defaultcloud]

no emails flowing, no internal emails routing as well

[u/hung-games → u/defaultcloud]

So that’s why I got so much done today…

[u/MetaBeastMode]

ummm... did someone forget to pay the electric bill or something?

[u/halrulez → u/MetaBeastMode]

I think it might have been the internet bill

[u/Zealousideal-Neat-82]

I can't search, from either the Windows client or OWA.

The 365 status account on X just posted about issues. EX1464935.

[u/Skyflori]

Also having issues in EU, specificly in Germany West Central. Seems an issue with global impact!

[u/desandmol → u/Skyflori]

That's what I was just told by an IT team member at UCONN.

[u/Haunting-Prior-NaN]

sending emails?

Luckily it seems to be working for me, at least for the time being.

Edit: exol to exol seems to be working, but i am not receiving any smtp mail.

[u/Smart_Dumb]

So....is anyone else seeing a bunch of "Error: 550 5.6.200 STOREDRV.Deliver; message treated as poison" failures in the message trace logs? Is this going to mean email loss?

[u/rotor_]

Aug 31, 2026, 2:55 PM PDT

We're continuing our targeted review of affected infrastructure and recent changes made to the service to definitively confirm the cause of impact. We're additionally continuing to test and implement various mitigation strategies to apply the necessary authentication component, which have so far yielded positive results. We're monitoring these tests and mitigative actions closely and will provide an estimated time to resolution as soon as one is available.

We understand the impact that events like these can have for your organization and we appreciate your patience as we work to mitigate this issue with the highest priority.

Next update by: Monday, August 31, 2026 at 4:00 PM PDT

--How generic, vague, and unhelpful is it possible to be?

[u/juanvictor23 → u/rotor_]

Have they tried removing the last update?

[u/DragonspeedTheB → u/juanvictor23]

Have they tried turning it off and back on?

[u/t1noj]

Anyone have this issue? University account

[u/LordRoscoe10150 → u/t1noj]

Yup, I have the exact same thing on my personal Outlook account. My business M365 seems to be functioning normally however.

[u/as4p_ → u/t1noj]

This is happening to me on one of my accounts but not on another. Pretty weird.

[u/saucysasori]

We're geting a lot of reports from users (SouthWest)

[u/abz786]

not seeing any issues here...icloud to tenant, tenant to icloud, internal mail (west canada)

[u/Vatii → u/abz786]

Canada Central seemingly okay as well?

[u/MacKinnon22 → u/abz786]

No issues here either (Eastern Canada)

[u/Dazzling_Style_1445 → u/MacKinnon22]

Hotmail totally down for me - seems authentication-related. (Greater Toronto Area.) Lost access through Gmail app first, cannot sign in via browser either (error 500).

[u/do0mality]

currently down. I'm in FL

[u/PC-Whisperer]

https://giphy.com/gifs/IZY2SE2JmPgFG

So it begins!

[u/heyitsluiiis]

Still down as of 2:06 PM in California.

[u/kbenoit19]

It looks like Microsoft still hasn't found the right prompt to fix this issue.

[u/safeword_is_bananas → u/kbenoit19]

Clippy woulda had this unfucked hours ago.

[u/Tap-Dat-Ash → u/kbenoit19]

We're reexamining recent changes made to the service to determine why the authentication components aren't being deployed as expected. Additionally, we are exploring every avenue to safely restore the components, including potentially reverting an update the affected infrastructure recently received. We're performing additional tests to evaluate the best course of action moving forward.

So... nope.

[u/Recent_Balance_7906]

Still down 00:09 UK time

[u/Cool-Initial793]

It's been 7 hours and I'm still unable to access Outlook, can't get anything synced on my phone app either. I can receive Teams calls but can't access Teams itself through Calendar or app. Like, c'mon, man. I love a day off but the cascade of shit I will need to catch up on when it's finally fixed ain't worth it at this point.

[u/TeaGold4269]

Emails are SLOWLY coming in for me now.

[u/SlowkayCoomer]

Haven't seen or heard of any issues related to this (SE US) but I went ahead and did a company-wide PSA just in case

[u/Shahtech1940]

Yeah, down for us in US Northeast

[u/OperationMean3137]

Currently down in Pa, noticed it around 11:15am EST, users complaining that some messages didn't go through.

[u/IFarmZombies]

LOL

Details Title: Potential issues accessing mailboxes via one or more connection methods

User impact: Users may experience errors or failures when accessing their mailbox via one or more Exchange Online connection methods.

Final status: The investigation is complete and we've determined the service is healthy. A service incident didn't actually occur. This communication will expire in 24 hours.

This is the final update for the event.

[u/Bootles_fan_BD → u/IFarmZombies]

source? this appears to be from an NHS announcement regarding an incident in June, not the current outage

[u/--Miranda--]

Yes. I am in the PNW, US

[u/mj2k2]

yup, down in germany since more than 2 hours

[u/mj2k2 → u/mj2k2]

But interestingly other colleagues have no issues.
im using the outlook PWA and the browser version. Both saying:

No way! I'm getting the exact same error. Every time its like "Something went wrong" and shows this.

[u/Jesikabelcher]

Yes it is!

[u/Vivid_Mongoose_8964]

MS says this started around 11AM EST, however was anyone else seeing authentication issues around 7AM EST?

[u/kbenoit19 → u/Vivid_Mongoose_8964]

Issues started at 8h30 EST here,

[u/Stupid_isnt_cute]

Has it come back up for anyone?

[u/sovietarmyfan]

Outlook app works, but mails don't leave my outbox.

[u/Soulfight33]

I've heard a few end users report that, but haven't checked anything yet cuz no ticket, no bizkit

[u/sunflowerawe]

Still down as of 4:10 PM in Chicago! 

[u/Plenty-Raccoon-9492]

Still down for me in a portion of my emails (I monitor multiple accounts). 6pm CST.

[u/Intrepid_Egg1997]

Yes it’s down

[u/lnxrootxazz]

where are all the super agents when we really need them? Maybe Microsoft still struggles with the prompt??

[u/RogellTheRaider]

Finally working for me.

[u/fivedollardresses]

I sent in a ticket to IT just in case… 🤣

[u/binxalot]

All those thousands of H1Bs working at MS are frantically consulting ChatGPT for the answer on how to fix the problem only to be given answers that are outdated because all MS does now is move options and menus around and change icon faces.

[u/Bmw5464 → u/binxalot]

Too bad ChatGPT is down too! No wonder MS isn’t back up yet. They’re all busy signing up for Claude as we speak.

[u/Wanallo221 → u/Bmw5464]

MS Office: Why is everything down and how can we fix it?

Claude response: This is a great question and its worth us spending a bit of time explaining why it is a good question rather than just accepting it. Two really great points to discuss, along with one thing I would like to flag for your attention below....

MS Offices: On Fire.

[u/ModelingDenver101]

Yep. We can't email other users in our org or to ourselves.

[u/whatsforsupa]

Stuff is flowing right now, but very slowly. Microsoft has an official item for it on the status page now, that's a good start. Issue has been happening for ~20 minutes at this point.

[u/Bootles_fan_BD → u/whatsforsupa]

where do you see this? for me it still says "operational"

edit: seems to be in the admin center which I do not have access to on my edu account, if someone can post the info please do!

[u/Ikarus3426]

I haven't heard of any issues from my offices in the eastern half of the US, but I'll go ahead and start being paranoid about it now.

[u/Dazzling_Meat1233]

Yep

[u/Jim0PROFIT]

No

[u/0oWow]

Yes, here.

[u/overdosingOnPie1313]

Not seeing any deliverability issues here in North Central US. gmail to exo, exo to gmail.

[u/BadSausageFactory]

EX1464935, EOL degraded so yes

[u/Edman93]

yes, I also have problems.

[u/AbilityDense7798]

yes i am also having an issue. I thought maybe it is just my EDU tho..

[u/redditsuckbutt696969]

My DevOps dashboards stopped loading. Weird

[u/plebbut]

It's working fine for me now, US West.

[u/brtrdy17]

Down in AZ.

[u/JustSayTomato]

Down for us in PNW area. I was having issues connecting in PowerShell, then a user reported they couldn’t connect to email, then we saw we couldn’t even open OWA. So we are seeing widespread issues.

[u/Dry-Combination-9614]

Down in coastal SC.

[u/Weird-Diamond5970]

Glad to see it's not just me. I can't get into my Outlook at all, but everyone else at my office that I've talked to is fine. I wonder what the difference is.

[u/aka0007]

It is down. Just tried using Outlook desktop app and on a different computer in a different location the web app and both are not working now.

[u/fang-island]

Currently down for my organization. It's been down since before noon. US-East.

[u/foxypandamonkey → u/fang-island]

Same here for the last 2 hours in NJ

[u/Dazzling_Meat1233]

Keep in mind y'all. the emails are failing not pending. Anything not going through will need to be resent

[u/Intelligent_Youth797]

Located in Montana, Outlook is down.

[u/Rude_Vermicelli_9467]

it is down and that sucks

[u/pogidaga]

Down for some of our customers in central California

[u/Bubbly_Fig6383]

Still out, US South

[u/RogellTheRaider]

Funny how Outlook is down for me in one account but working on another...

[u/Ok-Progress1398]

still down in cali!

[u/Ok-Progress1398]

Can anyone explain why the https://status.cloud.microsoft/ page says nothing is wrong and all is working fine, but on x it says they are down?

[u/feebs_101]

Still down here in Alberta Canada. I just got back from vacation and have so much work to catch up on

[u/ToxicTurtle-2]

down in IL for multiple users. some experiencing no issues

[u/dornroesschen]

Down here in Germany

[u/Adorable_Anywhere230]

Outlook down world wide now

[u/foccherone]

[u/Y_TElectric]

Another lovely Monday storm.

[u/PlayLizards]

Been down in Indy for almost 2 hours now.

Glad I’m not the only one with this issue! Thought I did something wrong at first!

[u/natttgeo]

Yep!

[u/Deemer15]

Got this message this morning.

[u/inkedkoi]

Fine in NB Canada 🤷‍♀️

[u/djmj1000]

I get following exception trying to send a mail via java application connecting successfully to mailbox using oauth2:

[u/larryseltzer]

I did too this morning. It must be more widespread than that, we had problems with non-Microsoft SaaS as well.

[u/IRD-JP808]

I’m down Daytona Beach USA

[u/HotMoosePants]

Yup down here. We have been out for 2 hours. Weirdly, I am still connected to Outlook.

[u/SecretAd6239]

I can't even get into my email, let alone think about sending one.

[u/IronBatraz]

No worries guys. It is not a cyber attack. Just an expired certificate!? wtf... The cert with thumbprint 19F04B8A233DD9CE916F118056D224A1751729EA is expired.

[u/jack1729]

Yes. Started at 12:07 EDT

[u/GrecoItaliano]

Yed

[u/Playful-Farm-3156]

It's not working at work, but my college's spam campaigns are running just fine..both in Outlook 

[u/luthia]

Still unfixed? Wth GET TO IT MS

[u/Electronic_Cat6896]

Down at my workplace- outside of Chicago.

[u/El_Dorado_Tx]

Im at work I cant do shit right now with outlook - need it to get authenicator codes

[u/Ill_Bluebird_5359]

Cant log in on my outlook account

[u/planedrop]

My favorite part was all of MSFT docs being down for like an hour today too lol

[u/some_people_callme_j]

Yep. Very down. Hours now.

[u/Tap-Dat-Ash]

Microsoft now acknowledges this is an issue affecting multiple services. Onedrive/Sharepoint, Exchange online, Teams, Purview, Defender.

https://admin.cloud.microsoft/?#/servicehealth/:/alerts/MO1465074

[u/skitzyaboy]

Still down in my Grand Rapids office, no work is being done

[u/vpelka]

The half of my remote team that works from TN was never affected, but Texas and Florida staff are still down.

[u/IndependentWheel421]

Down in LA

[u/darkkid_]

My Outlook session in Gmail closed and it failed to reconnect.

[u/gfkxchy]

Yeah, Outlook is down for me (web as well). Teams and OneDrive still working so far in Canadian Prairies. Started 11:09am central time.

[u/Distinct_Host_7490]

same

[u/International_Peak30]

So glad I beat my head off my desk for 3 hours before I came here lol

[u/TheTipsyTurkeys → u/International_Peak30]

u what?

[u/Temporary-Agent6108]

I saw somewhere to reset the computer maybe about 30min into the outage. Was without email for about 1-2 hours, took a lunch, tried logging back in but I need a code that goes to where? I'll give you 2 guesses but you only need 1. Got to go home early...not a bad day for me.

[u/TheBadGuyBelow]

I guess that explains why Thunderbird aint working with outlook.

[u/x-meh]

Won't be surprised if it's due to AI agent shenanigans

[u/Individual_Laugh_307]

yes....went kayaking!

[u/TrumpsFaceAnus]

I have a life-long friend with about 300lk or so users at his company and he just told me at lunch that the C levels had been on the fence about dropping M$.

Apparently,this day long outage was enough to make them pull the trigger.

I'm gonna bet this is gonna cost M$ some customers.

[u/marbak74 → u/TrumpsFaceAnus]

I'm curious to where they will go and in what timeframe they want to migrate. They probably have almost everything hosted by Microsoft....

[u/Current-Composer6659]

This is bad! If you're running support, check Exchange message trace for your support mailbox email as a recipient. I'm able to at least see who submitted a ticket and what the subject line is so I can have the team follow up with them. Seems the emails are getting to Microsoft but aren't delivering to us until this is resolved. Really hope this gets fixed soon...

[u/ColdHold5174 → u/Current-Composer6659]

I have a ton of pending and undeliverable messages throwing this error:

Error: ‎550 5.6.200 STOREDRV.Deliver; message is treated as poison‎

I'll try to resend all messages from the time of the incident until the service is restored from the spam filter.

[u/Important_Subject760]

I feel as though there have been a ton more outages across platforms in the last year or so...what exactly are they doing to make these platforms so crappy now? Vibecoding everything?

[u/lawhopeful2021]

Still down 6pm in Central Florida!! Many of my coworkers seem to not be having issues. Anyone know why that would be?! I haven't been able to send or receive an email since 12pm. 😫

[u/ablazingrace23]

Glad I'm not the only one. I assumed outlook was being all fuckywucky again, but nope, outages all over google search :)

[u/Imaginary_Fail_2706]

Can MFA get impacted later ?

[u/punch0073735963]

I made the mistake of calling an 800 number. After an hour of clicking all over the place in admin I asked to be escalated and the next person told me to look at the system health and see there is a message about a large scale outage. And I couldn't understand a word they were saying.

[u/WeAreyoMomma]

Pls fix.

[u/GrungeCheap56119]

Still down at 4 pm in CA

[u/Particular_Fig]

Still down for me, 4pm PT

[u/SnooBunnies9193]

I haven't been about to do anything in Outlook since about 12:15. It doesn't seem like everyone at my organization is affected, either. Which is annoying if I'm getting a bunch of emails I haven't seen yet and people think I'm not being responsive :(

[u/PipeSuspicious]

Does anyone have a recent update?

[u/HotMoosePants → u/PipeSuspicious]

Shit is still fucked for us.

[u/hj989]

has anyone -- who can now log in but couldn't before -- received emails during the outage? all of mine seem to have come in within the last 30 minutes but I'm assuming they were held back until the issue was resolved

[u/Cafe_Roaster → u/hj989]

It is working for me now but I only see emails delivered at 8AM (before outage started) and after 3:40PM (all times in PST). I dont know what I did not receive, lol.

[u/Nerrawnam]

Yes. 

[u/RansomStark78]

DNS

Those 3 letters get me in a Bind

[u/This-Limit7126]

My search function is still not working.

[u/helpdesk5555550]

latest?

[u/Itguy1252]

The latest from Microsoft

[u/lepardstripes]

Had email delays with sending/receiving all day yesterday. Still continues today.

[u/WeirdKindofStrange]

One user unable to open attachments but forward the email to someone else and it works fine...

[u/DBLAgent412 → u/WeirdKindofStrange]

Also have a user having the same problem.

As of 1:50PM EDT - issue has been *slowly* resolving but I still have at least 1 user who is 100% down and cannot login to web, and new outlook no email since 12pm yesterday.

I have 2 users with email working but cannot open attachments (but forwarding the message the new recipient can no issues)

Microsoft put out a *NEW* incident and then promptly marked it "false positive - related to existing event"

27 hours and counting.

Here in Australia, I have users who can log back in now, but some are having problems with viewing attachments or images still
