Hi there experts!

The problem is: 2 users, A and B in my domain with WinXP/Outlook 2003 (clients) and Win2K3 R2 on the server.   Haven't granted "Send As" permission to user B for user A but its happening... User B can enter in the "FROM" field in Outlook the name of user A and send email as user A.
I REALLY need to remove this. Any ideas??
Have already checked User A's properties,permissions etc as well as user B's in our Exchange 2007. Its all clear!

Thx!!!

Check your permissions on AD, you might have delegated some permissions to a group on the domain level.
