Is there a way to check for free space if I do not see this event?

Filter App Event log for 1221 events and see how much free space in the database is reported for that store. If it is more than 20% then it would make some sense to do offline defrag.
For temp file ("/tz:\temp.edb") you can use either local freespace or file share somewhere (plan for downtime accordingly to network speed and make online backup (to separate media) both before and after the defrag).

The actual RAID is rougly 340 Gb (Logs, page files, etc are on other drives), I have 16 database stores. Basically we have maxed out this server. The store I reference is only one of them, but it gets the most useage among corporate users. I have been archiving the largest mailboxes but I am not getting back any space. Online defrag runs tonight and I am hoping I can get a little bit more space...at least until I can convince Execs to spend the cash for more drives or another server altogether...looking for a little bit of ammo to strengthen the punch.
thx,

Free space in the store? If that's what you're asking, then an offline defragmentation is possible but unnecessary because the store would likely grow back to 50GB in a few hours.

Free space on the drive? An offline defragmentation would only work if there were more than, say, 45GB of free space in the database. However, you can map a drive to an share and use that as the temporary location through a command line switch and ESEUTIL would work fine.

Don't waste your time running an offline defragmentation unless you're going to get a substantial amount of space back. It isn't an activity you should need to be doing on a scheduled basis.

Hi,

If an Exchange Database is 50 Gb and the only amount of free space is 5 Gb,
is an offline defrag possible? After some reading it appears that an online
defrag is NOT possible, but I wanted to ask the group to confirm. Am I
mistaken?

thanks,

Mel
