Fix Group ID Not Found - Sync 365 / Azure AD

Group Mapping Error – Group ID Not Found

Error: GroupId not found – Username to Database update

This error occurs when a custom license or contact filter in Sync 365 is configured to use a Microsoft Entra ID (Azure AD) group that no longer exists or has been renamed.


Cause: The group reference used in Sync 365 (by display name or ID) does not match any group currently available in the customer’s Entra ID (Azure AD) tenant.

Resolution

To resolve the issue, fix the group reference by checking both Sync 365 and Microsoft Entra:

  1. Login to the customer’s Microsoft Entra portal
  2. Navigate to Groups and confirm the group exists
  3. Update the group name in Sync 365 to match the correct group in Entra ID:
    • Go to Custom Licenses or Contact Filters in Sync 365
    • Edit the group name to match what’s in the tenant

Once the group reference is corrected, rerun the license sync or wait for the next scheduled update.
