Hello Art,
Pls, confirm that in C:\ProgramData\Microsoft\Windows Server\Logs\SharedServiceHost-EmailProviderServiceConfig.log you find this error:
BecWebServiceAdapter: Connect to BECWS failed due to known exception : System.ServiceModel.EndpointNotFoundException: There was no endpoint listening at https://bws902-relay.microsoftonline.com/ProvisioningWebservice.svc?Redir=1098557810&Time=636356539931802459 that could accept the message. This is often caused by an incorrect address or SOAP action. See InnerException, if present, for more details. ---> System.Net.WebException: Unable to connect to the remote server ---> System.Net.Sockets.SocketException: No connection could be made because the target machine actively refused
If that is the case open regedit and go to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows Server\Productivity\O365Integration. Under HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows Server\Productivity\O365Integration\Settings locate BecEndPointAddress key and delete that. Now reboot the server and try again.
