Hello everyone, this is the case,if i have a company and i have employed a new domain administrator, when i joined this new admin to 'Domain Admins' group he enhirited full permissions on Exchange users including 'Send as' permission. Now this admin can use the 'From' feild to send emails as someone else which may cause a big problems. so how can i prevent that!! what permission settings shall i set up thanks in advance!

Hi,The solution depends on the version of Exchange server you are using."Send as" permissions for administrators are denied by default so some changes to default behaviour have been performed in your environment.This might help:http://social.technet.microsoft.com/forums/en-US/exchangesvrgeneral/thread/c5efdfaf-33e4-4b35-8535-57aaaece401e/Leif
