Hi gang! When I check the size of our EDB files in the MBDATA folder on our Ex2k/Win2k server, it's telling me my Priv.edb file is just over 12Gigs. But when I check the Event Viewer for the online defrag that runs nightly, it's telling me I only have 270megs of space free in the mailbox store. So, I'm assuming I better run a offline defrag SOON before my Exchange database reaches its 16 gig limit. I have to admit, I'm real nervous running the offline defrag and just want to make sure I have the correct command before running the offline defrag. Just so you know, I don't have enough disk space on the same drive that Exchange is on. In Exchange System Manager, right-click the information store that you want to defragment, and then click Dismount Store. At the command prompt, change to the Exchsrvr\Bin folder To defrag the priv.edb, enter the following; eseutil /d /p "e:\exchsrvr\mdbdata\priv.edb" /t"f:\tempdfg.edb" If there's anything else I should be aware or concerned about, please let me know.
