Environment: 1 ISA 2004 server, 1 Exchange 2003 Server also hosting the OWA site, 1 new Exchange 2007 Server with CAS/Transport/Mailbox/OWA
We are moving from Exchange 2003 to Exchange 2007 and have moved a couple of mailboxes for testing. Currently, we cannot access a mailbox on the Exchange 2007 server via OWA from the Internet. We CAN access the mailbox on the internal network with Outlook or OWA.
OWA access from the Internet is using SSL. We created a new certificate for the Exchange 2007 the same as was done years ago for the Exchange 2003 server.
If from the Internet, I enter: https://exchange2003.domain.org/schools this takes us to our Exchange 2003 server provided the mailbox is on it. If the mailbox is one that was migrated to Exchange 2007, a second prompt is provided to enter credentials and the browser just times out not connecting.
If I enter: https://exchange2007.domain.org/owa I get a page cannot be found error 404
If I enter: https://exchange2007.domain.org/exchange I'm asked for credentials but then it just times out again.
There are two seperate publishing rules on our ISA 2004 server for the external ip which directs to each corresponding Exchange server.
Hope someone can give me some things to check, we are wanting to migrate users to Exchange 2007 next week during our fall break at school.
