Hi,
Maybe I am a little confused, but we will have a case that doesn't seem to be covered:
1 Exchange 2003 that does OWA and mailboxes
1 Exchange 2007 server that will handle everything (i.e. CAS, mailbox, & hub).
I would think that this would be the most common scenario. In this situation can I just point everyone at the 2007 box (i.e. exchange2007.domain.com/exchange) and it will automatically redirect or proxy where appropriate?
I imagine that as I migrate mailboxes from 2003 to 2007, it will handle the redirect correctly. That is, user A lives on 2003 and when s/he logins in to exchange2007.domain.com/exchange s/he is proxied to OWA2003 UI. After migration, AD knows where the user’s mailbox is and upon logging into exchange2007.domain.com/exchange they are redirected to exchange2007.domain.com/owa.
Thanks,
Brad
