Microsoft Graph Data Connect App Registration Issue

Trent Tamura 20

How do you now create a Microsoft Graph Data Connect app registration? For context we had one working for over a year. And we tried to update the scope to add one AD Gorup to the scope, and it wasn't working. So we removed that app registration, and now for whatever reason using the exact same app, we are unable to create an app registration.

Microsoft has deprecated or altered some MGDC onboarding flows. You can no longer simply register the app manually in Azure AD and expect MGDC to work as before.

MGDC apps must be onboarded via the Microsoft 365 Admin Center or through Microsoft Fabric (for newer tenants).
Manual app registrations in Azure alone will not suffice unless properly linked to the MGDC provisioning service.

Steps to Recreate the Graph Data Connect App (2025 Approach)

A. Use Microsoft 365 Admin Center (Recommended)

Go to Microsoft 365 Admin Center > Setup > Microsoft Graph Data Connect

Follow the guided onboarding process for a new app registration.

This will ensure the app is registered with the necessary schema, permissions, and consent.

B. If You Must Register Manually (Advanced)

Go to Azure AD > App registrations > New Registration

Register a new app (avoid reusing the old one’s name or ID)

Under API permissions, add:

Microsoft Graph > Application > User.Read.All, Group.Read.All, Directory.Read.All

  `Office 365 Management APIs` > `ActivityFeed.Read`, if activity data is needed
  
     Microsoft Graph Data Connect permissions (select from Data Connect)
     
     Grant Admin Consent for the entire tenant

Assign Microsoft Graph Data Connect roles via AAD (in Enterprise applications > Your app > Permissions)

C. Use Microsoft Fabric (If applicable)

If you are using Fabric, the Graph Data Connect experience is now integrated:

Go to Fabric > Manage > Data Pipelines > Connectors > Microsoft 365 (Graph).

Provision through that interface, which handles backend wiring automatically.

If I create a new App in Entra completely with different name completely, can I use that and run the ADF pipleine and it create all of this automatically like it used to? Or can I create the MGDC app registration manually at the minimum?

For additional context. I createa a brand new app registration. Gave it the appropriate permissions, and API permissions. Created a new MGDC app registration (which worked this time), I then switched my ADF pipeline to use the newly created service principal. But I'm still getting in error in ADF that says:

ErrorCode=UserErrorOffice365DataLoaderError,'Type=Microsoft.DataTransfer.Common.Shared.HybridDeliveryException,Message=Office365 data loading failed to execute. office365LoadErrorType: PermanentError. Your application is not registered with MGDC. Please register your application following the instructions in aka.ms/mgdcdocs/onboardingexperience. For additional assistance, please create a new support request for Microsoft Graph Data Connect by following the instructions provided here: https://aka.ms/data-connect-faq.,Source=Microsoft.DataTransfer.ClientLibrary,'

@R. Cofrades You have to manage the MGDC application in the O365 Admin Portal. On the left panel go Settings>Org settings>Security & privacy (towards top of screen)>Microsoft Graph Data Connect applications. There was and still is very little documentation on this.
