Teams Connector: GraphUserDetailNotFound

So we implemented the Crisis Communication App ( and we are using the Teams Connector Post to Post your own adaptive card as the Flow bot to a user.


We know the Teams Connector is in preview but we sometimes get a Status code 400 error when posting the card to a user:

  "error": {
    "code": "GraphUserDetailNotFound",
    "message": "No user details with email or UPN '' were found in Graph."

Strange thing is that on MAY 14 one of the users failed, while on MAY 6 the Flow finished successfully for all 393 users including the failed user on MAY 14... is this a known issue that Graph Connection / Team Connector is buggy?
