Power App sharing & permissions for guest users - Questions

Hello community,

There's a few question marks in my mind for guest users using Power Apps. From what I have seen and tested, you can share Power Apps to external guest users in your tenant and they can access the Power App through a Teams channel for example.

Now, the problem/question is that, can guest users have normal access to the connectors required by the Power App? My Power App uses the following connectors:

Microsoft Dataverse
Office365 Outlook
Office365 Users
Office365 Groups
Microsoft Teams
SharePoint
OneNote

In theory, if the guest user has an appropriate license (Microsoft E3 or E5 for example) and a Power Apps per app plan -license, they should be able to use the app and the connectors normally or are there some limitations? Recently I shared a Power App (with the connectors listed above) to a guest user that had E5 with Power Apps plan 2 trial -license and there was an error with the Office365 Users connector for example to fetch information about the current guest user.

Would anyone be able to give some information/solutions to my problem?

Thank you in advance,

Ville

There are a few extra wrinkles when working with external users, but it sounds like you have the licencing one figured out. Here are some other things to check:

The external users must be added to your tenant's AAD

Check for security & DLP policies that restrict/prohibit external users from doing certain things. If those are different than internal users, you could run into problems.

Data sources, such as SharePoint Lists, must be shared with the external users that use them as part of the app's use

Expect extra restrictions around the Office365 Groups/Users connectors and you may need to play with the Graph Explorer with various credentials to get an understanding of what specific items may be restricted.

Hope that helps,

Bryan

Hi @VilPel ,

You need to add the Guest User is Azure AD. Also you need to share all the connetors/flows/SharePoint List if any to Guest user. Else they will not be able to use it.
