Hello, I am using Exchange 2003 A/P cluster in 2003 domain. Today i saw from System Manager that A user (neither a administrator nor a operator) seems like log on different mailboxes. This is user is very simple end user. He has a mailbox and is member of some distrubtion and security groups that are not related to Exchange or Domain Administration. I checked Domain and Exchange Security configuration but i didnt see his name and account. How can i diagnose this problem. Which log or events should i track? Thanks

Hi, I assume that you refer to the last logged on info under mailboxes in system manager. This is normal behaviour - the system manager logs this when a user opens another calendar/mail folderfor which the user has been given permissions or when the user schedules a meeting. Leif
