Configure the system so that you can create an iView for the Outlook Web Access client.
Single sign-on is not possible with Outlook Web Access on Microsoft Exchange 5.5. This uses a logon.asp page for user identification before the user can log on to Web Access. The page with user information persistence is root.asp. This page redirects to logon.asp every time the user starts a new session.
This redirection process replaces the browser session and the user is logged out of the portal session.
If you are using Exchange 2000, this issue does not exist and the following changes are not required.
CheckSession2 = CheckSession3(bstrRedirectURL,"top",-1)
with new code so that that the FRAME gets replaced with logon.asp instead of the entire browser window
CheckSession2 = CheckSession3(bstrRedirectURL,"self",-1)
