I am trying to give a user in Exchange Server 2007 SP1the 'send as' permissions for two other users who happen to be domain admins (only similarity I have tied to the problem accounts). However a short while after granting this user the send as perms, it gets removed from the list and the user is no longer able to send mail as either domain admin. Can anyone offer any insight as to why this may be happening? I have granted this same user send as perms on mail accounts that are not domain admins and there doesnt seem to be a problemwith those.Thank you for any help.

Read Microsoft Articles 817433 and 281146. Whatmost likely ishappening is that Domain admins are part ofthe protected group, and their acls are being reset every hour. This is a throwback to the same issue everyone saw with the BlackBerry "SendAs" issues a while back when a patch came out in Ex2003. BTW, personally, I don't think it is a great idea to change Domain Admin's security, but that is up to you.

Are you aware of any other ways to accomplish what I am trying to do short of removing the users from the Domain Admins, or adjusting Domain Admin security? Thanks again.
