Is it possible to simply force https://exchange2007/exchange to point to the local 2007 mailboxes instead of immediately redirectingto the exchange 2003 server? After the migration, I would like to use the same URL they have always used to access their webmail instead of giving out the /owa name. Some people hate change....

See if this Article can hep you out in simplifying the OWA URL on exchange (according to your wish)http://technet.microsoft.com/en-us/library/aa998359.aspxRaj

Thanks i'll check that out.If left alone, will the https://exchange2007/exchange address continue to point to legacy email server once all mailboxes are migrated? If so, how about whenever the legacy server is removed later on in a few weeks?
