All Users except admins cannot send via smtp - MS Exchange 2010
Posted on 2014-03-10
I am using thunderbird for the smtp mail client. I have it running on the exchange server itself. When i use my admin account i can send mail. If i use any other account i get the error "the mail server responded: 5.7.1 client does not have permissions to send as this sender...."
My exchange connector is set up for anonymous users and exchange users.
Why is this? Thank you.
