I recently had to restore a 6GB mailbox to my Exchange 2000 server. Once I had finished with the content of this mailbox (printed off a couple / moved a couple to PST etc.) I then cleared the contents of this mailbox. I did this by using Mailbox Management, identifying all message older than a day and action "delete immediately". In Exchange System Manager, the size of the mailbox was reduced from 6GB down to about 2MB. I was surprised to find that the following night, the online defrag utility reports 2,218MB of free space after online defrag.

I am not interested in physically shrinking the size of the databas files - I know this requires an off-line defrag. I am concerned that I do not now have about 6GB white space as surely this amount has been removed the message database ? The amount of legitimate e-mail written to the database in between the delete and the defrag would be way below 1GB so this does not account for it.

Because I chose "delete immediately", there is nothing in the mailboxes deleted items, there is nothing showing in the deleted items recovery option either. However, I have "Keep deleted items for 35 days" set on the mailbox store (and it would fall in this period). Is this the problem ? Is there a way that I can report the space being taken by messages that may be in this condition (deleted but not "purged") ? Is this was the case, is there a way to purge only for this mailbox ? I keep deleted mailboxes for 0 days - If these messages have not yet been "purged" would deleting the mailbox free the space up within a day (bearing in mind the message are technically no longer in the mailbox ?).

Any help would be much appreciated.

Again, I understand that the size of the database files will not be reduced without an online defrag. I am not intersted in this, I just don't want to grow the files any bigger by having insufficient white space.

Many Thanks,
