Unable to find email address - Exchange 2007
I've a strange email address problem in Exchange 2007.
I have a problem that whenever I email a particular user I get a ďMail delivery failedĒ message straight back but from the userís old Yahoo account.
Iíve checked the delivery forward options within Exchange 2007 and itís blank (no forwarder set)
Iíve checked the userís local Outlook rules and still no forwarding rule.
Iíve checked for a contact with this email address and found nothing.
Iíve done a check via the Exchange Management Shell and Get-Mailbox ĖIdentity and found nothing.
Iíve searched Active Directory via a Custom Search and LDAP query (proxyaddresses=smtp:firstname.lastname@example.org) and still found nothing!
I cannot think of anywhere else to look, anyone offer any advice?
