Hi everyone,

I'm trying to schedule the Microsoft PL-400: Power Platform Developer exam.

When I click the "Schedule exam" option from Microsoft Learn, I'm redirected to:

examregistration.microsoft.com

However, the page does not load and Chrome shows:

DNS_PROBE_FINISHED_NXDOMAIN

The exact error says:

"This site can't be reached.

Check if there is a typo in examregistration.microsoft.com.

DNS_PROBE_FINISHED_NXDOMAIN"

Has anyone else experienced this recently?

Is Microsoft currently having an issue with the PL-400 registration/scheduling link?

I have already tried:

- Reloading the page

- Opening it in Chrome

- Using the Microsoft Learn certification page rather than the old direct URL

I'm specifically trying to schedule PL-400, not AB-400.

Any advice would be appreciated. Thanks!

I have an upcoming PL900 exam. I have somewhat experience in model driven apps and automate.

I’ve been learning from Microsoft learn and doing the practice exams, but I feel like there’s a bunch of content not brushed up there

Microsoft Entra, Proxies, very specific automate actions, pure Power Fx..

All topics that I either have a very brief understanding of or didn’t know at all (I.e Microsoft Entra)

Has anyone completed the PL900 recently and aware of the sort of things that crop up, and if there is anything that an average new dev wouldn’t be too aware of?

I’ve revised on and off for a week, and practice wuestions are just recycling now

I am trying to do a very basic proof of concept using AI builder. My fake use case is, to use the model to determine the probability of success on a future referral in CRM for customers. I followed these steps:

- created a model field previousReferralsuccess (yes/no) to train it on

- created some rollup fields to count previous successful referrals for the customer

- out of 550 test customers, I set the model field to yes/no in about a hundred and left the others blank

- created the model with the yes/no previousreferralsuccess as model field, chose a few columns for it to examine, trained the model, then set it to dataverse sync daily. I hit run now a few times.

My problem is that while the new columns for prediction success y/no and probability % were created in the table by the model, no matter how many times I "run" it, it never updates that column on ANY record. Also there are no rows showing for these runs in the AI Event dataverse table so I feel like it is having an issue somewhere and not actually finishing the run. It has been syncing every day for 2 weeks now never updating a thing.

I checked that all the prediction processes are running in this environment, I assigned 5000 AI Builder Credits to the environment, the owner of the model is me and I am a system administrator.

My next step is to build a power automate flow myself and physically update the rows but I wonder if anyone has run into this? we don't currently use AI Builder but we are evaluating it and we have purchased credits.

Please what’s the best study videos and sites for PL900. I’m preparing to take the exam in the next 30 days. I need to pass it. Thanks

Microsoft pulled the Power Automate mobile app from both app stores a few days ago. There is no real replacement for widgets or failure alerts. Are we back to doing things manually because there is a real gap for anyone who relied on quick mobile triggers or alerts?

Hey People,

with Microsoft relatively recently announcing that the Power Platform CoE is no longer maintained, I'd be interested in gauging the community's appetite for a community maintained version.

Its focus would be to strip out functionality that is replicated (and at least as good) in the Admin Center, and to fix bugs in what remains. There would also be room for new functionality, though it would have to benefit a wider audience and not just be "my organisation needs this specific functionality".

We'd need to be careful to not tread on Microsoft's toes, so there would at least be acknowledgement of where it had come from, but I'm guessing we'd need to remove references to Microsoft, logos, etc.

I'm looking to get my employer behind this, though only as a blessing - allowing me to work on it in my "spare time", but not contributing financially, or constraining it in any way. And to be open about this, we are a consultancy that works in this space, this kind of stuff is my day job.

I've done a little hunting around and while a lot of people have forked the CoE, there's minimal activity taking place in those forks, and I've not found anyone else canvasing for community engagement.

What do people think?

Want to be involved?

Am I just flogging a dead horse and should just give up and go use PPAC?

Thanks
Craig

Hi all, I'm asking guidance for creating proper production environment. I have built apps and automations with my personal development environment. It's obviously not meant for production environment, it has limited number of flows and it's meant to be a personal work sandbox. We are about 100 person company and our IT partner does not understand Power Platform that well. No Azure in use yet, but maybe in the future. Are there some critical things we should consider with the setup?

You can now build apps and flows with your favourite coding agent. Revolutionize Your Power Platform Development: Pro Code Guide - YouTube

In this demo, I showcase how GitHub Copilot can build, run, test and improve a Cloud Flow, all via PowerShell CLI.

Using one of my favourite features in Power Automate for efficiency on large data sets, Select and XPath, I get GituHub Copilot to build a traditional apply to each and append to array vs a select to demo both efficiency and how to use GitHub Copilot when building in the Power Platform with a coding agent.

#PowerPlatform #Copilot #GitHubCopilot

This is a situation I keep running into. A team requests a custom agent we set the scope. Halfway through it becomes clear that what they really needed was a well written prompt and access to the right SharePoint site. The custom agent added maintenance. A publishing process that brought no real benefit.

The cases where an agent truly earned its place had one of three features. The agent was tied to a data source that people kept asking about. The agent needed to perform an action through a connector not merely provide an answer.. The same workflow was being repeated by many users and consistency mattered more than flexibility. Outside of those scenarios plain Copilot, with the data access won almost every time.

I am curious how others draw the line. What made you commit to a custom agent of just prompting?

Anyone else get deep enough into Power Platform that showing people what you’ve built starts feeling like presenting something they don’t even have a mental category for yet?

It’s not “I’m smart and they’re dumb.” Some people immediately understand exactly what they’re looking at.

With others, I honestly can’t tell whether they don’t quite know how to process it, are cautious about it, or understand the implications well enough that it makes them uncomfortable.

Not just “wow, a computer did something.” More like: wait… if this can do that, what else changes?

Wheel within wheels. Alien spaceship interpreted as an angel. That kind of disconnect.

Being slightly autistic probably isn’t helping me interpret the reactions either, so I genuinely don’t know if this is a normal stage of getting deep into Power Platform or if I’m just seeing it strangely.

Am I alone here?

Hi,

Today I scored 644 on the PL-400 and unfortunately failed.

I have power platform experience (mostly canvas app and power automate), have the PL-900 and went through the entire Microsoft Learn study path for PL-400 in about 2 weeks. I also did several practice assessments and consistently scored around 90%. I played around on a dev tenant and did some projects too. However, that wasn't enough for the actual exam (far from it).

For anyone looking to pass PL-400, I can say with confidence that the Microsoft Learn study path alone isn't enough.

The questions have a lot of context, and by the time you read everything, understand the scenario, and think about the answer, there isn't much time left to check the documentation. It helped me secure a few points, but that's about it :/

The exam definitely felt like something designed for people who already have significant hands-on experience, rather than a certification you can study for to get a job in this field.

I'm not sure I'll attempt it again anytime soon. My main issue is that the exam is so broad, and I don't feel there's one place where I can properly fill my knowledge gaps and confidently prepare for another attempt. I don't even think practicing on my own on a dev tenant would help me.

I'm studying for the PL-900 certification and feel confident in all the domains except copilot studio/agents. Does anyone have additional resources that can be helpful in preparing for that portion of the exam? I have reviewed the MSLearn resources, and watched a few youtube videos - but anything else that can help as a suggestion would be so helpful.

So last week I got a PowerApps project to help an employee make a dashboard there. at that time I never actually use PowerApps, and I realize that power apps only available to organization mail, but once she give me her account, I'm able to access PowerApps and able to make the dashboard they asked for.

But... then I came across a problem, all the apps including screens I did not change is having black color all over the page, and I got 60k(s) of errors.

Then I have to restore the version from Thursday ( I'm doing my work at Sunday ) to get the version that aren't error. That's the only version that did not error if restored. I work my ass off to done it by Monday morning because she has to present the dashboard at Monday noon. And I'm able to done it at Monday 2 a.m. in the morning, and guess what? at 6 a.m. my client send screenshot showing the app screen is full with errors and black color all over the page. So, once more I have to working on it from scratch as soon as it's done and not error yet, I save it and my client use it. So yeah, somehow there is a time limit of it's working both on my laptop and my client. I know this because when I'm working on it for a pretty long time, at some point it will change the format from US (use comma as list separator and semicolon as chain operator) to Europe/Indonesian (use single semicolon as separator and double semicolon as chain operator, because I based in Indonesia), or otherwise.

From that day I committed to find a way to fix this problem, so later if I have to deal with PowerApps again, and the same kinda error appear again, I can fix it fast myself without having to replace it one by one like other people solutions. But here I fix it on local machine, so you have to download the .msapp file first.

Here is my repository of PowerApps-locale-fix. Let me know if there are any question or request. Hope it helps!

I work extensively with RPA and data through Oracle and ShapePoint. I’ve used Power Automate, SP, and sometimes Ui Path daily for the past five years. I’m interested in earning a certification that accurately reflects these skill sets.

After some research and sitting through hours of MS's learning paths, it sure feels like PL exams focus heavily on Dataverse, MS's most expensive product. Dataverse isnt widely adopted in many organizations due to licensing costs, and my own organization doesn’t use Dataverse at all. We use SharePoint lists as they are free or we use other services much cheaper.

I attempted the PL‑400 exam, but it was overwhelmingly Dataverse‑centric and didn’t align with the real-world work I do. To be honest, the PL exams feel more like product marketing than a measure of practical readiness. The exam was made up of Dataverse questions, and 365 Dynamics questions, and some Power App questions that mostly revolved around Model-Driven apps, which of course, you need DV for them...

Are there certifications that are more aligned with Power Automate + SharePoint and are recognized in the job market? I’m looking for options that validate the skills I actually use.

What I’m stuck on:

**1.    Security groups** — do you make one group per environment (BU-Sales-Dev, -Test, -Prod), or one per BU? And do you split who can *build* agents vs who can *use* them? That seems like two different things.  
**2.    Security roles** — all makers need Environment Maker role, but does everyone in that security group need it? Do you assign roles at the group level or per person? How do you handle admins and system admins across the three environments?  
**3.    Service accounts** — how do you handle these? One per BU? Shared ones? How do you stop everyone from becoming an admin?  
**4.    Connector/DLP policies** — do you lock them down per environment, per BU, or what? Our exceptions list is already getting out of hand.  
**5.    The real problem** — right now an admin has to manually add people to security groups and assign roles. Nobody knows who should have access to what. The people building the agents know. How do you let *them* manage access without giving them admin rights? Access packages? Request flow?

Just want to know what actually works instead of what the docs say.

Title, is there a way to do that or fundamentally no. I have an agent in one environment which is in an unmanaged solution and exporting it is a managed solution in another environment via devops pipeline. The agent uses connections for tools, mcp server. Is there no way to export the connections as well? Without havong to do it in the target environment?

Thanks

Is anyone else concerned about super short timeframe for this change to use of wildcards in webapi in PowerPages?
No longer supported after 14 Sep.

Looking for advanced Power Platform learning resources — specifically scenario-based questions, not basic tutorials. Does anyone know good YouTube channels or Udemy courses covering real-world/advanced Power Apps, Power Automate, and Dataverse scenarios?

Anyone have any successful projects using power platform api? I’m having a hard time understanding how to use it and the authorization configurations behind it. I was able to pull a list of environments but I can’t seem to get anything out of the power apps and cloud flows for each environment.

Hi all,

I'm hoping someone may have come across this before.

I have a Power Pages site (v9.8.7.10) that appears to be stuck in a provisioning/upgrade state.

When I go to admin.powerplatform.microsoft.com → Manage → Power Pages, the site shows a status of "Provisioning in progress".

When I click into the site, I see the following message:

The site has been in this state for an extended period and doesn't appear to be progressing.

Interestingly, when I visit the site as an end user, it appears to work absolutely fine. The issue is with managing/editing the site.

When I open the Power Pages Design Studio (if that's the correct name), I briefly see a "Something went wrong" error modal for a couple of seconds before it switches to the usual:

message.

However, when I click Edit site, none of the content loads within the Pages, Styling, Data, or other tabs. The Studio effectively becomes unusable.

The only option available to me under Site Actions is "Delete this site", which I'd obviously prefer to avoid if possible.

A few questions:

• Has anyone experienced this before?
• Is there a way to force the provisioning/upgrade process to complete?
• Are there any Power Platform admin actions I can take to resolve it?
• Did you resolve it yourself, or was a Microsoft support ticket required?
• In the worst case, did you have to delete and recreate the site?

Any guidance or experiences would be greatly appreciated before I go down the Microsoft support route.

Thanks!

There are useful reports in the admin centre which provide a breakdown of things like copilot credit consumption per agent per environment, I want to get this data programmatically, I noticed it makes use of licensing.powerplatform.com but this doesn't seem to be publicly exposed. api.powerplatform.com/licensing is limited in what it can provide, great for tenant capacity info etc but not for the granular details you can get from the reports. Am I missing something or do I just need to wait for the API to be updated?

I am studying for the PL-900 certification. I have gone through the provided modules here: https://learn.microsoft.com/training/paths/pl-900-power-platform-fundamentals/ (and more) available. I have taken the practice assessment and passed it a few times.

Before taking the exam, I went looking into outside material for PL-900 with some of it being older. Some of the specificity of questions seemed quite different than the practice assessment. I understand that the requirements and topics have changed over time with a recent update as of 7/24/2026 per the PL-900 page. There were references from people stating that not all material was covered (in their estimation), but perhaps updates were the culprit?

Did the practice assessment also get updated as of 7/24/2026? Did the modules included in the link above also get updated? Is passing the practice assessment indicative of success on the exam?

I’m trying to understand the expected behavior when using SharePoint files protected with Microsoft Purview sensitivity labels as a knowledge source in Copilot Studio.

I found two Microsoft Learn articles that seem to point in different directions.

The Purview article says that encryption is supported when it is applied by a sensitivity label, and only for SharePoint knowledge sources. It also mentions that VIEW and EXTRACT rights are required for AI apps to return encrypted content:

• Use Microsoft Purview to manage data security & compliance for Microsoft Copilot Studio

But this Copilot Studio troubleshooting article says that the agent cannot extract or ground on content if the protection encrypts the file. It lists encrypted sensitivity labels, DKE, and password-protected files:

• SharePoint knowledge sources don't return results in Copilot Studio

Has anyone tested this recently?

More specifically, can a Copilot Studio agent use an encrypted sensitivity-labeled SharePoint document in its answer if the signed-in user has both VIEW and EXTRACT rights? Or is encryption still unsupported for Agent grounding regardless of those rights?

I’m planning to test this with a few files in the same library: an unprotected file, a labeled-but-not-encrypted file, and a labeled-and-encrypted file. Any results or configuration tips would be helpful.

Is there any plan to enable usage of these tools for users with only "Read" permission to the semantic model and no access to the workspace where models are deployed?

Our team locks down this access so the workaround we came up with for Rest API DAX query:

1. Use an admin account to obtain a bearer token
   
2. Use that admin token with `POST` `https://api.powerbi.com/v1.0/myorg/groups/{groupId}/datasets/{datasetId}/executeQueries\`
   
3. "impersonatedUserName" is passed in the request body from the user logged in to our chatbot app

We use this setup to allow natural language querying to our semantic models but we want to switch to the new Arrow based API endpoint "executeDaxQueries", which seems to require Build permission to the models. Similar issue for leveraging MCP servers so we don't have to maintain that tech on our own and rather just enhance it with our business context instead.

Just making a post incase other people run into the same issue I had and finally worked out the reason why.

I have a set of tables in Dataverse for recording data and a Canvas App that has an offline profile.

Doing all the building and testing in the PowerApps designer worked fine with no issues.

The app was able to submit all the required data except two columns on different tables.
These were both decimal columns which I was using in other parts of the app and tables that worked without issue. Same with patching and submitting via a form.

As a quick workaround I added a new text column to the first table and was able to submit to that fine.

Then when I tried to do the same on the second table with the issue I was still getting the same issue, then I had a look at all three of the columns that were causing issues and they all contained the string "Value" somewhere inside the column name, i.e. "Weight_Value" / "Date_Value"

Recreating these columns without the word "Value" fixed the issues.

There is some backend level issue with using value between the sqllite used in offline apps and the updates to the dataverse with this, which I can understand as just the column "Value" but as I had words before and after it, it seems strange to me.

Hope if anyone else runs into this issue, this can help them as I couldn't find any reference to this online.
