Description
MAGE will not sync a user(s) and you may see errors similar to the following:
"Invalid value was specified" or "Error Microsoft.Exchange.WebServices.Data.ServiceResponseException: An internal server error occurred. The operation failed."
-
Cause
The UserPrincipalName (UPN) may be missing on the source or target accounts, preventing the MAGE from logging on and returning the errors. -
Resolution
Check that your users have their UserPrincipalName attribute on the source and target users and that you can logon with this particular UPN format via EWS.
