I am using an ASP page that uses CDO to access a user&#039;s Exchange Inbox. It uses basic authentication on the web server to log into Exchange. I create a CDO Session object, login to it, retrieve the messages in the user&#039;s inbox, logout, and kill the Session object. I take all the precautions I can to logout and kill the objects if an error occurs. However, after a while of people using that ASP page, Outlook&#039;s Web Access (OWA) no longer works. You can still bring up the login page for OWA, but it will no longer validate and login any users. Both OWA and my ASP page are running on the Exchange server&#039;s IIS. A reboot of the Exchange server will get everything running fine again for a while. Then OWA crashes and we are back where we started.<BR>Any help would be greatly appreciated. If you need more info, let me know. Thanks.
