Operating in a mixed Ex2003 and Ex2007 environment
(I had previously posted these questions as part of another thread, "Re:
Questions about migrating from Ex2003 to Ex2007 and coexistence. - more
questions", but I think they got lost in the other information)
We're in the process of planning a migration from Exchange 2003 to Exchange
2007. For a period of time we'll be operating with both environments in
place.
I have a couple of questions related to operating in a mixed Exchange 2003
and Exchange 2007 environment.
I know for Exchange 2007 user mailbox settings you have to use the Exchange
07 tools, you don't use the A/D users and computers snap in, but during the
"coexistence" phase, I assume I still use the A/D snap in for the Exchange
2003 users, correct? If we need to create a new user, or mailbox enable
someone on the Exchange 2003 system, do we just use the regular tools?
Also, regarding OWA. I realize that the Exchange 2007 CAS provides for the
backward compatibility 2003 "/exchange" OWA site, but due to our licensing
issues I don't want to run the 2003 users through the 2007 web system. Is
there any problem with leaving our 2003 Outlook Web server active and as we
migrate users and at that time have them go to the 2007 CAS server (and use
the "/OWA")? What would happen if a user with a mailbox on the 2007
server would try to access the 2003 OWA server?

Mike, yes continue to use the "regular" tools for managing/creating Exchange
2003 users.
Also for Exchange 07 users access an OWA 2003 server..this will not work.
OWA 2003 does not have the capability to render pages for Exchange 07
mailboxes.
Thanks,
Jason

Re: Operating in a mixed Ex2003 and Ex2007 environment
Thanks. Both answers are pretty much what I figured, I just wanted to
confirm. We don't use OWA extensively, mostly management or staff who what
to check their email from home, or occasionally from out of town. However,
when we start telling people to use "/OWA" instead of "/Exchange", I KNOW
there's going to be ones who use /exchange then wonder why it doesn't work.
I was hoping there would be some process where the Exchange 2003 would
recognize that the mailbox is on a different server and redirect their
access to the new one.

Re: Operating in a mixed Ex2003 and Ex2007 environment
I know the Exchange 2007 can handle both "flavors" of OWA, and the intent is
to migrate everyone to the Exchange 2007 eventually, but due to budget
issues, we can't migrate everyone yet. I don't want to send (potentially)
all 4500 Exchange 2003 users through an Exchange 2007 system with only 160
Ex07 client access licenses.
