All, I want to run a defrag on my priv1.edb file, roughly about 80GB. How long should I expect this take? My server is not speed demon (P4 with 2GB RAMBUS RAM and 300GB of IDE Drives). Thank you for any help, Ferrocki

If I recall correctly 4-6GB an hour, it all "depends" for 80GB I wouldnt do it on a weeknight, more like a weekend night.James Chong MCITP | EA | EMA; MCSE | M+, S+ Security+, Project+, ITIL msexchangetips.blogspot.com

I agree with James on the generic estimate. Why do you want to defrag? Have you looked at event 1221 to see if you even have much space to reclaim? Offline defrags are not part of routine Exchange maintenance. You only need to do this if you are running low on disk space AND 1221 tells you you've got a lot to gain.

Thank you so much for your answers. I've been deleting old accounts off (around 20GB) and I was thinking I would get some space back and clean up the DB. Ferrocki
