Send as self not allowed
Posted on 2012-08-20
I have a user that needs to use an alternate domain as his primary send as smtp address. He also needs to be able to use his current default address from time to time. I currently have the alternate domain address set as his default "Reply". When we go in and change the "From" field in Outlook to use the original domain we will receive a rejection with, "You are not allowed to send this message because you are trying to send on behalf of another sender without permission to do so."
Seems pretty odd as the "From" address is the old primary domain that he would normally send from, but since I changed the "Reply" address to the other alternate domain he can no longer send as the old primary.
Old primary: domain1.com
can send as firstname.lastname@example.org no problem, however can not send as email@example.com???
