  Hi Nitish

  1. Yes you can use the same certificate.  It will need to include a legacy hostname (normally legacy.domainname.com) for 2010 -> 2003 redirection

  2. This is possible but not as easy an in 2003.  See http://briandesmond.com/blog/redirecting-owa-urls-in-exchange-2010/

  3. The login page will come from your 2010 CAS then they will be redirected to the current OWA 2003 interface.

  Cheers, Steve

  You may also need to enable Form Based Authentication on your Exchange 2003 server in order for OWA redirection from 2001-> 2003 to work properly (I had to enable FBA on my Exchange 2003 otherwise it would not redirect properly).

  one thing to add, be sure to check your firewall because some firewall will not allow the redirect from HTTP to HTTPS.

  Agreed, unless you are using ISA/TMG in which case basic auth should be used instead.
