question on going past mailbox store size

[chipperjonesrules]

I had our mailbox store set for limit of 73 gig. yesterday I got the notification we were at 72 gig.
I had people clear out a lot of email, several gig, but didnt knock down the Deleted Items Retention to 0 thinking the online defrag would get us though.

well it didnt, mailstore dismounted. I increased the limit to 73 gig,everything came back up. and it appears we were still receiving emails all along, as I look and see incoming and outoging emails after the mailstore dismounted at 5 am.

so, finally, the question:
if we cleared over 5 gig, wouldnt the online defrag have created us some whitespace? or is it all just because we didnt set the deleted items retention to 0?

What do the event ID 1221 entries say in the log? That will tell you the amount of whitespace.

Keep in mind that if people deleted items, those items are still in the dumpster, and taking up space until DIRT passes.

well, the store dismounted on 2-5-11 at 5 am.
that is when I got Event ID 9690 stating that the size of the database had exceeded the limit of 73 gig.

on 2-5-11 at 4:15 event 1221 told me I had 12 meg free space on the public store.

the last time I saw 1221 on the mailbox store was 2-4 at 6 am, stating that 1348 meg free.

event 704 occured on 2-5-11 at 5 am stating that

Information Store (5224) First Storage Group: Online defragmentation of database 'D:\Program Files\Exchsrvr\mdbdata\priv1.edb' was interrupted and terminated. The next time online defragmentation is started on this database, it will resume from the point of interruption.

so something stopped the defrag of the priv1 edb file, and following that we were over the limit and the store dismounted.

so possibly if the defrag had not failed we wouldnt have had this issue?

Your database size is (file size - white space). That amount can't exceed 75GB. Enforce mailbox limits so that (# of mailboxes * mailbox limit !> 74GB). Drop your DIRT setting to a lower value. Delete mailboxes for terminated users. Wait for online maintenance to clear the dumpster of some data.

would this error keep the offline defrag from working?
