Sharing a PowerApp Canvas app with an external/guest user - not working

(0) ShareShare
ReportReport
Posted on by

Hello,

We are building a PowerApp Canvas App within our Microsoft 365 E3/E5 subscription and are attempting to share the PowerApp Canvas app with a guest/external user - however, it is not working.  Here are the steps we have taken for testing.  A support ticket has been opened with Microsoft, but the recommendation is the same steps - republish or share/unshare.

 

1. Created a PowerApp Canvas App with only one button - no data connections.

2. Saved and Published the Canvas App

3. Within Azure AD, invited a guest user that does NOT have an Azure AD or O365 tenant

4. Guest user accepted the invitation and they appear as a "Microsoft Account" in the Source type (viewing the account within Azure AD)

5. Then we have assigned a PowerApps Plan 1 license to that guest user (either in Azure or O365 admin portals)

6. Then we share the app with the guest/external user

7. The external user receives the invitation notice that a PowerApp has been shared with you

8. The external user clicks the link, logs into with their Microsoft Account authentication

9. Spinning circle for PowerApps appears and then the following error appears:  "This app isn't opening correctly" "It looks like you don't have access to this app.  Ask its owner to share it with you."

10. Looking at the browser F12 developer tools interface - there are a number of warnings and errors.  The most interesting error is:  "Failed to load resource: the server responded api.powerapps.com/api/invoke:1 with a status of 403 ()"

 

Does anyone have any suggestions?

 

As a sidenote, if we invite an external /guest user that has their own O365/Azure AND an O365 license for PowerApps, the guest sharing works perfectly.

thanks,

Matt

    Hi Mona

    Thanks for the reply.  Yes, the Guest account is being "auto suggested" when I invite it for sharing.

    Also, all the steps for the reference docs article have been followed.

    thanks,

    Matt

    Hi @Anonymous .

     

    When you type the user account in PowerApps site to share the app, will the auto-suggest show? If the user is already invited as a guest to the tenant the auto-suggest feature will present guest names and indicate the user is a guest. 

     

    Also make sure that you are following the latest documentation here:

    https://docs.microsoft.com/en-us/powerapps/maker/canvas-apps/share-app#share-with-guests

     

    Notice:

    The guest user must have a license with Power Apps use rights that matches the capability of the app assigned through one of the following tenants:

    • The tenant hosting the app being shared.
    • The home tenant of the guest user.

     

    Regards,

    Mona
