Can anyone help me with this issue? An employee at "company" tried to send an e-mail to an employee at "company2". The e-mail bounced. If you notice, the to line clearly shows the recipient as company2. The error message said it couldn't find the user at company. I manage both domains, and there is no trust between them, however, the DNS servers at company do look at the DNS servers at company2 (and vice-versa), as we have a p2p VPN connection between the two domains.
This didn't happen until recently, and this is relatively soon after we upgraded company from Exchange 2003 to Exchange 2010.
Any help would be appreciated.
