We recently changed an email address from a Security Group to a full mailbox. Users who have used the address in the past are now receiving bounce back mail, we have been delete the nickname email one by one as and when however to do this for all users will be hard.
Does anyone know of a was we could include the removal of the address in Group policy or in a .vbs file etc etc... any ideas??
