MS Exchange 2007 Receiving Error 550 5.4.4 ROUTING.NoNextHop; unable to route from one user
Posted on 2008-06-13
We have client that is running MS Exchange 2007. There are other users that can e-mail to firstname.lastname@example.org. However when one user e-mails to this address he receives the following error:
Diagnostic information for administrators:
Generating server: server.domain.LOCAL
#550 5.4.4 ROUTING.NoNextHop; unable to route ##
All users are using MS Outlook to access their Exchange mailbox to send the e-mails. Any help or direction to look would be greatly appreciated.
Thanks in advance.
