We are in the middle of a migration from Exchange 2003 to 2007. The migration is probably going to take the next two weeks, and we would like users to have access to OWA during this time regardless of where their mailbox resides. Currently we have:
* 1 Exchange 2003 FE server
* 3 Exchange 2003 BE servers
* 1 Exchange 2007 server with Mailbox, Hub Transport, and Client Access roles
* 1 Exchange 2007 server with Mailbox and Hub Transport roles
I have moved some mailboxes of former users to one of the 2007 servers for testing. I have shut down the FE server and added its IP address to the Exchange 2007 CA Server. Now from the internet I can access https://webmail.company.com/owa
to get to mailboxes on the 2007 server. I cannot get to the mailboxes on my 2003 BE servers. I expected that though, and according to the documentation I've read, I need to hit the /exchange folder instead to be redirected properly. I tried that, and I get an internet explorer Page Not Found error. I also tried accessing https://fqdn/exchange
locally and after supplying credentials, I also get the Page Not Found error. Any ideas on how I can get this working for both 2003 and 2007 mailboxes? I should add that we can't really afford any additional hardware/licenses for this. Thanks!
