Exchange hybrid - on-premise mailbox issue

Both ExchangeGuid for on-premise Mailbox and MailUser are same.
Any ideas?

Not sure that you have this correct. MSOLUser is the user in AAD (found using get-MsolUser cmdlet). The mail user should be the same user but found in Exchange Online using the get-mailuser cmdlet. If you have TWO users found in AAD (and possibly EXO) with the same details, then you have a problem. Check the AAD Connect health to see if there are any sync errors. You might see an indication of duplicate addresses or user type mismatches
