Hi, I notice some user(s) are using my Internet connection heavily by connecting to my Exchange 2007 OWA. I am wondering if there are any tools to see who are actively using OWA? I could dig into IIS's log files but they are not very user friendly. Thank you!

From my experience, that's a hard thing to determine any way except the IIS logs because OWA sessions aren't persistent, i.e., the client doesn't maintain a session with the server like with MAPI.Ed Crowley MVP "There are seldom good technological solutions to behavioral problems."

Hi Puzzled, How about use the get-logonstatistic, some information for you: http://technet.microsoft.com/en-us/library/bb124415(EXCHG.80).aspx Regards!

Upto some extent you can also use ExMON tool also.

Ed, Thanks for the explanation. It makes sense about OWA not being persistent. Gavin and Harisha, Thank you both the the tips. I tried get-logonstatistic but can't quite figure out how to display webmail only data. The output seems to be long. I notice ExMon does not monitor web user, though: "ExMon measures only MAPI traffic and load on an Exchange server. It does not include or display data about other protocols, such as Simple Mail Transfer Protocol (SMTP), Distributed Authoring and Versioning (DAV), Outlook Web Access, Post Office Protocol version 3 (POP3), or Internet Message Access Protocol version 4rev1 (IMAP4)."

Hi, How about Glen's work on the get-logonstatistics cmdlet ? http://gsexdev.blogspot.com/2009/03/sanitizing-get-logonstatistics-cmdlet.html ilantz
