Hi All :-) I am trying to give a user (User1) the 'Send As' permission to another user (User2) in my Exchange 2003 organization. I am doing this by going into AD Users and Computers and adding User1 into properties of User2's Security tab and checking 'Allow' next to 'Send As'. Our Active Directory is fully Windows Server 2003 (it's also the domain function level of the organization - Server 2k3) Here is my issue - After double checking things this morning, the User1 isn't in the permissions list of User2 any more. Does anyone know why something like this would happen? Should I go about giving the 'Send As' permission another way?? Any help at all is greatly appreciated. Thanks guys!! Rich
