We're in the process of setting up Exchange 2007, we currently have our production Exchange 2003 server running. Our 2003 OWA URL is mail.domain.com which is accessible both internally and externally. When we attempt to login in with a test user configured on the Exchange 2007 box, we log in then get a Windows credential dialogue box we have to enter domain\user and the password, then get redirected to the 2007 OWA login (so three logins in total.)My question is this; can we use the same URL mail.domain.com for both 2003 and 2007 users and allow redirection based on the user's mailbox location? If not what's a good solution while we complete the transition?

I dont think of an issue (which can create problem)in case you are using the same URL for both 2003 and 2007 OWA.Raj
