Hello 1. Browse to following place in registry HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\MSExchangeWeb\OWA 2. Add a DWORD key PublicClientTimeout or PrivateClientTimeout depending on which type of sessions time out you want to increase. 3. you can put time out value in minutes. 4. Save the changes and restart IIS. This should work for you. http://support.microsoft.com/kb/830827Thanks Mhussain
