Hello - I really messed up on this one and I need your assistance.
A couple of weeks ago I setup an account in AD and Exchange 2010 we'll call Public (email@example.com). I didn't notice this at the time, but Exchange automatically gave it the address of firstname.lastname@example.org because email@example.com was already in use. Since then, our Media department sent out advertisements with firstname.lastname@example.org on it for people to email.
The person who monitors this email address reported today that she hasn't gotten any emails to the new account. She sent a test email to email@example.com and it didn't arrive.
When I looked into that account in Exchange, I noticed that the address for Public was firstname.lastname@example.org. When I tried to change it to email@example.com, I get an error saying:
The proxy address "SMTP:firstname.lastname@example.org" is already being used by "domain.local/Microsoft Exchange System Objects/Board Requests". Please choose another proxy address.
Board Requests is the name of an Exchange bulletin board, but when I look at that, it is not mail enabled.
How can I find where the address email@example.com is being used so that I can change it, thus allowing me to adjust the account called Public to have firstname.lastname@example.org?
Thanks for your help.
