Here’s how you can find if users have the correct access to a Model-Driven App assigned or not. This becomes the first line of troubleshooting when a Users say that they are not able to access an App.

Let’s see how to use this!

In order to check a Users’ access to a certain app, make sure you a Dynamics 365 Administrator and has access to the environment in the Power Platform Admin Center (https://admin.powerplatform.microsoft.com/environments)

App Access Checker

Here’s how you can check in the Power Platform Admin Center which user has the correct access to the Published Apps in Power Platform.

1. Enter Settings by first selecting the desired environment where you want to check a User’s App Access.
   
   
   
2. Then, look for Users.
   
   
3. Alternatively, if you had clicked on the Environment name and entered the Properties, you’ll also find a Users link directly.
   
   
   
   
4. Then, you’ll see the option for ‘app access checker’.
   
   
5. Now, you’ll see a simple textbox which asks for the User ID of the user in the org whose access you are expecting to check.
   If you notice the URL, you can also bookmark this shortcut to your org’s name
   <a href="https://<orgName&gt;.crmhttps://<orgName>.crm<regionNumber>.dynamics.com/WebResources/msdyn_AppAccessChecker.html
   
   
6. Once you enter and check, you’ll be able to see the status of the results.
   
   
7. And you’ll see the details per app.
   

Hope this helps!

Thank you!
