Is invisible delegate driving you nuts? Users will get a bounced message from Exchange Server for a mysterious delegate, like one below.

Problem is a delegate’s mailbox was deleted and/or user account is disabled. Exchange mailbox is still having “hidden SID” about the disabled/deleted delegate information (in the current Boss’s mailbox).
Solution is easy. You will have to use Exchange Management Shell (powershell) to overwrite new existing delegates list.
I have seen on other forums that people are asking how do you remove an disabled delegate. You can’t remove the invisible delegate. You can only overwrite the delegate list.
- Open Exchange Management Shell.
- Type Set-Mailbox -Identity "Mailbox Name" –GrantSendOnBehalfTo <Delegate User Names separated by coma>
On the command above, you have list all active delegates user names separated by coma.
E.g., Set-Mailbox –Identity BossMan –GrantSendOnBehalfTo “ExecutiveAdmin1”,”ExecutiveAdmin2”
