Try the IIS log on the Client Access Server (CAS), which can normally found at C:\WINDOWS\system32\LogFiles\W3SVC1. Open the log for the day in question, it normally logs the page the user is accessing, the domain account they used and the IP address they connected from John.

IIS logs wont tell you everything. Diagnostic logging in Exchange will. when using diagnostic logging you will get a lot ov information. In real life you need something to filter those events you're intresting in. You also need storage for all logs since they take up space. lasse at humandata dot se, http://anewmessagehasarrived.blogspot.com
