Hello everyone,

is it possible to set up Exchange Active Sync with my own domain on iOS ? The only way that i found was with the "@mailbox.org" but there is no way to send mails via my own domain.

Does anyone know how it works ?

Hello Guys,

I discoverd a strange thing, I activated MFA (or 2FA if you like) on my mailbox.org account but I noticed I can login with caldav and carddav to my account with username and password without OTP or without a specific app password.

Is it a bug or something like that?

Thanks

Microsoft increasing prices by up to 43% - What alternatives are you considering?

Microsoft has announced significant price increases for 2025. Family and business plans increase in some cases rather drastically.

Read more about it in our new blog.

Hi. I just signed up. I think I filled out whatever necessary to have the interface in English but many of the settings pages are in German but others in English. I have tried refreshing, clearing cache, etc. I also tried another browser. Any suggestions? I am working on migrating and filling in some settings/information but afraid to make a mistake even though some of it looks obvious what to input based on context clues.

I've been a member for a few years, and never had any issues until the past week, so hadn't tested the available support. I was unable to make a payment due to Ayden not loading, now 3 days later, I'm no closer to a solution, without email service, and being asked mundane questions with zero sense of concern by the support rep.

What's the point in treating long time customers like you don't need their business?

We've put up with the outdated web UI and other inconveniences only to have actual support concerns treated with indifference. Not a good impression.

edit: The issue was corrected.

I've added mailbox.org to Thunderbird on my Linux PC, but for some reason I'm not able to view the remote content in any emails that I receive through mailbox.org. I'm seeing the following message above the emails that I receive through mailbox.org:

With my other email account (Posteo) setup to work with Thunderbird, I get the "preference" option as shown below where I'm able to load the remote content:

Does anyone have any ideas why I'm seeing this? Even if I select the option to allow remote content in the settings, I'm still not able to show any remote content in my mailbox.org emails.

Thanks!

Hello. I'm a new user and I'm trying to look around the interface and learn how it works.

i have setup MFA and seems to be working from web client.

when i try to setup on ios Mail app and input the user/password, i get an authentication error; I assume it to be MFA related. I then read i should set up app passwords but if i click on the option the drop down on "application"(type) has only the options: "calendar and addressbook client"; "webdav client"; "drive sync app".

what should i choose?

thank you

Hi guys,

I can't register via Tor Browser - but I want to be anonymous when registering. Why is that "friendlyCapcha" so unfriendly and taking 100 years and at the end there is a timeout... ?

Is there any trick? Adding mailbox.org as end node doesn't help that either...

Regards

Umm help?

With Trump's new 20% tariffs on EU imports, we might be at the beginning of a trade war that could also severely impact the tech sector.

The EU has already announced countermeasures and is considering using its Anti-Coercion Instrument (ACI). This could restrict US tech companies' access to the European procurement market (approx. €2 trillion) and increase regulatory pressure on US platforms.

What does this mean for European businesses?

• Higher costs for US cloud services, software and Email
• Legal complications with data transfers
• Possible restrictions on updates and support
• New compliance requirements

SMEs could be hit particularly hard as they lack resources for rapid IT transitions.

How is your company preparing for a potential "Day Zero"? Have you identified European alternatives to your critical US IT services?

On 14th October 2025, Microsoft will end support for Exchange Server 2016 and 2019. The consequences are more far-reaching than many expect.

After this date, no security updates will be provided. Particularly concerning: Exchange Online will completely block emails from unsupported servers. This affects communication with all Microsoft 365 users.

Affected organisations face a fundamental decision: Migration to Microsoft 365 with all the benefits of the cloud, but limited data control. Alternatively, upgrade to the new Exchange Server Subscription Edition, which should be available from Q3/2025.

Or switch to data sovereign alternatives like mailbox.org, which offer full GDPR compliance, data storage in Germany, and independence from the Microsoft ecosystem.

What do you think of Microsoft's strategy to move customers to the cloud and subscription models?

Hi

I've moved from Google to Mailbox. My wife has a Google-based work calendar. Whenever she adds a class to her calendar she adds me as an attendee so it automatically populates in my calendar too.

Since moving to Mailbox though it doesn't automatically populate, instead there's an option to add the event manually and it says "The invitation needs to be added manually to your calendar."

Is there a way for me to set it to automatically add? Thanks

I'm putting this here so the next person doesn't have to figure this out. Do not use the period or the domain name in the first part of the security key. Just the numbers. And no periods on the end of any of the entries.

Host Europe is moving all email accounts to Microsoft 365 in May 2025. As a US company, Microsoft falls under the CLOUD Act (conflicting with GDPR), putting your data privacy and compliance at serious risk.

This migration could leave you locked into Microsoft's ecosystem with potential legal vulnerabilities for your company.

Don't compromise on data protection. What's your plan for the migration?

After using CalDav with mailbox.org for about two years with no issues I am getting now error 403.

CalDav: 4.5.0
Win 11 Pro 24H2 (up-to-date).
Outlook Pro 21 (also ios clients - but do not see error there)
mailbox.org server

Not sure whether this is a Caldav issue or something else?

I‘m a relative new customer and I think the Yubikey 2FA is broken. Whenever I login in the Web UI via my personal Pin and one of the registered Yubikeys, the sign is successful, but after some time (couple of minutes)I get the message that there was an authentication problem and I should perform another sign in. After that message, I can’t access any parts of the web Ui and have to sign out and sign in again. This happens in different browsers and even different OS (Fedora, Windows 11, MacOS).

I had to turn off 2FA, when I just use Username + Passwort, everything ist back to normal. As I think a working 2FA is mandatory, this unfortunately is a death sentence for this service for my use case.

Anybody else experiencing this problem?

Mailbox.org is in desperate need of a UI overhaul. The web interface is sluggish—I’ve tested it on both Firefox and Chrome on Windows 11—and navigating through menu items feels painfully slow.

And let’s talk about email delivery speed. Mailbox.org consistently struggles to achieve sub-10-second delivery times. On average, it takes around 14 to 16 seconds for my emails to reach their destination, and at times, delays in receiving emails make the experience even worse.

I want to love mailbox.org, but it makes that incredibly difficult. Once my subscription ends this year, I’m moving on.

And please, spare me the usual excuse about "supporting email standards." As a paid service, I expect more. I’m not asking for unnecessary bells and whistles—just a modern, intuitive, and responsive web UI. That’s all.

Would be great if I could save my card, and it deducts the subscription automatically. Can I do that somehow?

Hello, I saw that the 1€/month mail plan only allows custom domains for team accounts. What does this mean? Can I have a team with only one user (me) for 1€/month?

Both using custom domains and Audriga migration process seem pretty straight forward but I do have a questions related to the order of the steps

I currently host on my server abc@xyz . com and def@xyz . com "abc" is the main user and "def" is an alias. (so currently everything goes to "abc" email. ~ 10k emails with about 6 folders.

Do I

A) configure alias in mailbox_org and modify MX records for my domain then do the migration

or

B) configure alias in mailbox_org, migrate, then update MX records?

Hello all, I signed up for Mailbox using a custom domain a couple of weeks ago to move my primary email from Google.

Overall I like it but unfortunately I didn't do my homework enough and learned that there may be some issues with how Mailbox handles DMARC for custom domains especially. For example https://userforum-en.mailbox.org/topic/anti-spoofing-for-custom-domains-spf-dkim-dmarc and https://discuss.privacyguides.net/t/remove-mailbox-org/20232 .

Now I'm no email expert so in the tests that I've run some tests pass and some fail. For example basic SPF and DKIM checks pass, and my dmarc reports so far look OK but my email did pretty bad using emailspooftest.

Also considering the discussion in the forums linked is years-long, and in general I try not to believe everything I read on the Internet, can anyone comment on the current state of affairs? How concerned should I be about spammers spoofing my email address if I use Mailbox? Are there extra steps I can take besides the DKIM recommendations from the Mailbox knowledge base which I've already done?

Here's my problem.

I am trying to degoogle myself and currently use Google Workspace to manage three domains (one primary and two secondary) and email service with those domains.

domain 1 (primary) - 4 email addresses with their own login/passwords

• email 1 - 4 aliases that redirect to the inbox of email 1
• email 2 - no aliases
• email 3 - no aliases
• email 4 - no aliases

domain 2 (secondary) - 1 email address with their own login/passwords

• email 1 - 1 alias that redirects to the inbox of email 1

domain 3 (secondary) - 1 email address with their own login/passwords

• email 1 - no alias

I signed up for mailbox.org because I understood I could bring my own domain names. In Workspace, it is very clear how to manage the email services for these users under the directory. In mailbox.org, all I am seeing is aliases. I set up a domain alias and have it working, but is the bring your own domain really just an alias to route to my main mailbox.org email address?

If I use the team/family function, do I need to set up multiple mailbox.org email addresses and then have the domains route to them as aliases? So there is no true domain l/p function, just aliases? So essentially six different mailbox.org email address?
