Exchange 2007 Update Rollup 4
Update Rollup 4 for Exchange Server 2007 is now available. The rollups are cumulative, so you only need to install this one to catch up.
There is an issue noted that if deploying silently or through WSUS and a file needing to be replaced is in use. In this case some services for Exchange will be stopped and disabled. Check KB Article 940006 for details on the problem and fix.
