Does anyone know of a way to produce a list of clients with a current OWA session?? Either via PowerShell, vbscript, Shell ... Thanks

I would imagine there are better answers out there, but you could enable logging and simply look at the logs in IIS. http://support.microsoft.com/kb/324279

Thanks, it's a start. I'm hoping some scripting guru will come up with a script that gives active connections/sessions.

Sorry to crowd your postings, but also you can servers server name storage group mailbox store logons look at login and log out time. on the far right, you'll see http as client version...

You're not crowding at all. Yes I saw the advanced page and the fields avaiable - very helpful. But can you tell me why the time posted in the log files is wrong? The time on the IIS server is correct.
