Exchange in Terminal Server Environment

I have a customer with a 2003 Standard edition server running TS, We are also running exchange and would like the users to use OWA in the Terminal Sessions.

When a user logons to OWA, the main screen show’s up fine. When they try link to another page the get a page not found error.

When a user logon directly to OWA outside the terminal environment everything works fine.

Any Thoughts?
