We had a chap (Nigel) who took 6 months off.
While he was away we routed any mail sent to his SMTP adresses to another chap (Stuart).
We did this simply by deleting Nigel's smtp addresses and recreating them under Stuart's account. No problems, worked like a charm.
Nigel has now returned, so I've now essentially reversed the process, but although the new adresses are correct and have been accepted by the server, it keeps sending all Nigel's eMails to Stuart. Almost as if the SMTP adress list in AD is being cached somewhere.
I've tried restarting the server, but no joy.
Any ideas anyone?
