Hi, I recently scanned through my Servers' event log and noticed that there is a warning on my CAS Server (Windows 2008 SP2, Exchange Server 2007) as posted below. It does not impact performance and is not causing any issues as yet. Is it safe to ignore it or is there a solution to rectify this issue? Appreciate any expert advise, I am not handling the exchange servers btw. Event code: 3005 Event message: An unhandled exception has occurred.
