Also posted on microsoft.public.exchange.connectivityHello. On a single-server solution with Windows 2008 and Exchange 2007 we are unable to log on to owa. We immidiately get the message 440 - session timeout. I've read several articles but they all refer to resetting the password on the iurs and iwam users, but those are (as far as I can see) not present in Windows 2008. Can anyone please help me with this problem?

Anytime I have issues with OWA, I usually start by making sure that IIS is working correctly. Can you try the default URL for the server, eg. http://servername/ Jim McBee - Blog - http://mostlyexchange.blogspot.com

Hi,Can you access the owa on the CAS server? (https://localhost/owa)What's the result?For this issue, please refer to the below article to troubleshoot this issue:http://support.microsoft.com/kb/941201ThanksAllen

No I can't access owa from the cas server, same error.I have fixed it now by comparing the IIS security settings with a server where OWA worked as intended. By mathcing the IIS permissions the error disappeared and OWA works now again. :)Thanks for all help, and pushing me in the right direction :)

Hi,Glad to hear that this issue is resolved by self.Thanks for your sharing.Allen
