When trying to remove a SMTP email address in the Email Addresses tab of the
recipient's properties, the Exchange Administrator hangs. It allows me to
remove the address, but when I click OK to exit the recipient's properties
it hangs and I have to end the task in the Task Manager.
I've checked technet but couldn't find anything. The server is running SBS
4.5 w/Exchange 5.5 (SP3).
Any help would be much appreciated as urgently need to update the recipient
of a key email address.
