Hi All, I want to run a batch file that will take the exhange "priv1.edb" store offline, defrag it and then remount it. I will do the same with the public store but less frequently. My first thought was to just stop the "Microsoft Exchange Information Store" service, run the offline defrag, and then restart the service. Any problems with this method? Alternativeley, I would prefer to dismount each individual store, do a defrag and then remount that specific store without affecting the other stores. Any ideas would be appreciated? At first glance, the first method seems a bit rough to me. Regards Steve
