Hey everyone.

Running Exchange 2007.

Now I have 2 users that cannot send mail - they are able to send mail only if we add their user accounts to Domain Admins in AD. Now obviously I dont want to do this.


Here is the error message they get when they are out of the domain admin group in AD.

550 5.7.1 Client does not have permission to send as this sender



Can anyone give me any information. I have googled it but I cant seem to find somethign that actually tells me what to do.
