I am running low on hard drive space on the drive that Exchange is installed on. My plan is to add a RAID1 drive(s) and mount it as the directory exchange is installed on. (mounted as D:\Program Files\Exchsrvr) and move all of the files from the orginal directory into that drive. How can I go about doing this? I'm guessing I'll need to boot up in safe mode so that Exchange will not be running so that I can rename and copy that folder, but can you add and remove drives in safe mode? Or can I just stop all of the Exchange services and then be able to tweak with the folder? Thanks, Matt
