Internal OWA in a mixed Exch 2003/2007 environment

I am about to move users from Exchange 2003 to Exchange 2007. Until the migration is finished I will be on both versions.

I know that in a mixed environment when using OWA internally I will get an error with but if I use or I get to the OWA logon screen.

Is there some way to have /exchange (or /owa) appended to the internal request for  ?

Yes there is. You need to go to the IIS thats receiving the (2003 or 2007) and redirect all requests to (if its 2007) or /exchange (if its 2003)

heres for IIS7:

heres for IIS6, exchange 2003:

when you have installed an exchange 2007 it is make requests for owa
dhruvarajpCommented: can not be used for both /exchange and /owa

you might want to recirect /exchage to
and /owa to

i know it is dificult to tell what use should go to what url

so that should be part of your migration plan and tell users when will they be
using the new url webmail

Thank you
Problems using Powershell and Active Directory?

Managing Active Directory does not always have to be complicated.  If you are spending more time trying instead of doing, then it's time to look at something else. For nearly 20 years, AD admins around the world have used one tool for day-to-day AD management: Hyena. Discover why

in a co-existing environment, even if users try http://servername/exchange, it will be redirected to http://servername/owa.

Yes. Mkris9 is right. In a coexistence envoirement if users type http://exchange2003/exchange and their mailbox is on 2007 they will be redirected to http://exchange2007/owa
In a coexistence of exchange 2003 with exchange 2010 this is not true.. but as far as i'm concerned in exchange 2003 with 2007 this happens.

Ok, for some reason I am now getting a "Under Construction" error when trying to access OWA from an Internal address. From the Internat I get to OWA just fine.....

GreatVargas:  In your first message you mentioned this:

heres for IIS7:

But it seems to refer to Exchange 2010 on Server 2008, I am running Exchange 2007 on Server 2003 R2
