We have a user who has had access to his old mailbox restricted by management. However, they want them to continue to receive mail in a new mailbox using the same SMTP address.
The situation is, the old and new mailboxes both exist, so internal mail is still going to the old mailbox when using the autocomplete feature in Outlook, for people that have typed the SMTP address previously.
What is the process for moving the X400 internal address from the old mailbox to the new one, so that we don't have to get the entire company to clear their autocomplete cache?
I have tried simply changing the X400 address on the new mailbox to match what it was on the old, but has proved fruitless. I have also added an X500 address matching the X400, but guess this is not correct.
Any help is appreciated. Thanks
