An issue cropped up that I need your help. Have Server 2008 Standard with Exchange 2010 plus AD installed. I have a user whose email address is firstname.lastname@example.org and his login (user) name is bob. Here is the issue: The user is receving and sending email with email@example.com AND firstname.lastname@example.org. As administrator, I did NOT add email@example.com to his AD SMTP email addresses. The address with firstname.lastname@example.org is the "default" email address in Exchange.
How did the email@example.com get in the SMTP if I did NOT add it?
I now need to determine, I assume from the "sent" folder, all the mail that was sent under firstname.lastname@example.org so that I can blast email to them that the correct email address is email@example.com. What is the best way to do this? Your help is most appreciative. Many thanks in advance for your support.
