Outlook web access 2007 and 2010 addresses are configured through the web proxy function of SSL VPN. After a user logs in to Outlook Web Access 2010, the user fails to log in to Outlook Web Access 2007. The system displays a message indicating session timeout. This is because Outlook Web Access 2010 reserves user authentication information in the browser buffer and such information cannot be processed by Outlook Web Access 2007.
If the user wants to log in to Outlook Web Access 2007, perform the following operations:
Log out of Outlook Web Access 2010.
Close the browser and re-open the browser and log in to the SSL VPN gateway.
In the web proxy list, click the Outlook Web Access 2007 address and enter the user name and password to log in to the email account.
