Hi, Any ideas why our dedicated Exchange 2007 Server has all of a sudden mysteriously gained an extra 60gb of free disk space? Or where I might be able to look for some hints? Thanks in advance

Hi, Where are you see extra space , Its in LOG drive or DB ? Please check event log to see for more details. If you are finding space increased in LOG drive then it must be issue of backup. Check your backup whether log purged in time. Also can check offline defrag of DB is see issue in DB size and white space. http://www.msexchange.org/tutorials/Defragmenting-Exchange-Database.html http://technet.microsoft.com/en-us/library/aa997972(EXCHG.80).aspxAnil
