Problem

Customer receives the following error when running an MS Graph delta query, for instance the following:

GET https://graph.microsoft.com/beta/users/delta
'error': {
   'code': 'Request_UnsupportedQuery',
   'message': 'Change enumeration is not supported for requested tenant.',
   'innerError': {
      'request-id': 'xxx',
      'date': '2020-05-22T13:17:45'
   }
}

Root Cause

This error can happen if the tenant is an Azure AD B2C tenant.

More Information

Differential or Delta query is currently not supported in an Azure AD B2C tenant. It only works for a regular tenant. There are some discussion of this in the following links:
