Hello. We currently have a single Exch 2003 box with OWA on it. Users access OWA via https://outlook.mydomain.com/exchange.
I am planning my Exchange 2007 migration. In the process, I need to move mailboxes from 2003 to 2007 gradually (over several weeks). While doing this, I STILL need users to be able to access https://outlook.mydomain.com/exchange to get their email via OWA, REGARDLESS of whether their mailbox is running on the 2003 or 2007 server. It is my understanding, from technotes I have read, this is possible, but ONLY if I place my CAS role from Mailbox role on different servers. *IF* I try to combine these roles on one server, then it won't work (I assume the users with mailboxes on 2007 will NOT get their email properly) because the /exchange virtual dir will not properly redirect to the /owa virtual directory for my 2007 mailbox users. I draw this conclusion from --> http://technet.microsoft.com/en-us/library/aa998849.aspx where is details the /exchange virtual dir. Based on that, I believe I need to seperate my CAS role from my Mailbox role (at least until the 2003->2007 Migration is complete) in order to continue using just a single OWA URL during the migration process. Can someone clarify if I am understanding this correct?
