Can verify the same error is received when attempting the POST via Graph Explorer.

Hi @Thomas Dorsey

According to my tests, this error only occurs when both "RequireSignIn" and "SendInvitation" are set to false:

Therefore, double check your request body to make sure "RequireSignIn" and "SendInvitation" are not both set to false.

Hope this helps.
