Hi all, is there any way can check which accounts (users) is using POP3 or IMAP4 to setup the account? As I would like to disable the features, and only allow Exchange type, so I want to verify who is still using it. Thank you! Thomas

I've never tried it, but you can probably use protocol logging. http://technet.microsoft.com/en-us/library/aa997690.aspxOutlook Web Access For PDA , OWA For WAP www.owa-pda.com email a@t leederbyshire d.0.t c.0.m

Hi Thomas, I had tested this issue before: In my lab (Exchange 2007 SP3 and Outlook 2007 SP1): The Authentication for POP3 and IMAP4 services are : Plain text logon(Basic authentication) After I enable protocol logging for pop3 and imap4, I can see the information of Data-time, Connector-id, session-id, sequence-name, local-endpoint, remote-endpoint, event, data and context are all included in the logs, and find the users who login under the context. Here is a related thread for you, hope can give you some help: how to show current logged users using imap protocol http://social.technet.microsoft.com/Forums/en/exchangesvrmonitoring/thread/4b566940-4571-4a50-b473-0dcf40bdc446 Thanks, Evan
