Ok, so I have a user account called sales. And that user account has two email address, email@example.com and firstname.lastname@example.org.
The user account's primary SMTP address is email@example.com.
We send out email blasts to our customers from this address. We would also like to send out email blasts from the firstname.lastname@example.org but it keeps returning the message that I don't have permission to send as this user.
Why can I send as one email address and not the other?
We've been doing this without any problems for the last 5 years. But last weekend we upgraded from exchange 2003 to exchange 2010 and now this doesn't work.
I've browsed over every nook and cranny of the Exchange Management Console and can't seem to figure this one out.
Any help would be appriciated.
