Hi
I am in the process of transitioning to Exchange 2007. I have a single
exchange 2003sp2 server and I have installed Exchange 2007 on a new server.
I have reached the point where I have moved a test mailbox from the Exchange
2003 server to the Exchange 2007 server. I am able to send mail from the
mailbox on the exchange 2007 server to a mailbox on exchange 2003 but not the
other way.
When attempting to send a message to the Exchange 2007 user i get the
following message returned
Your message did not reach some or all of the intended recipients.
Subject: RE: direct again [Scanned]
Sent: 12/03/2008 10:57
The following recipient(s) cannot be reached:
ExchangeTest on 12/03/2008 10:57
The e-mail address could not be found. Perhaps the recipient
moved to a different e-mail organization, or there was a mistake in the
address. Check the address and try again.
<conc-exch-001.concorde.internal #5.1.7 smtp;501 5.1.7 Invalid
address>
The user on the exchange 2007 box is still listed in the address book.
The exchange 2003 based users are all functioning ok when sending mail to
each other and sending and recieving external email.
I am using a smarthost and this is configured in the SMTP connector on the
exchange 2003 server as the exchange 2003 server is the server I want to
handle incoming and outgoing smtp until I am ready to switch.
I have probably missed something very simple in the transition process so
far but I can't see what it is at the moment. It's slightly annoying as when
I created a sandbox environment on virtual server it all seemed to go so well!
Any help would be appreciated.
