When right clicking on the actual mail store the DB shows 62GB, the total in the report fromSBS shows 80GB, obviously there is a concern it will stop working and why the discrepancy? The event ID's showing the offline defray do not show 13GB difference, possibly 5GB of recoverable.

Mailbox size is edb file + stm file - free database space
The value in eventviewer is the correct one.
Also look in registry what the actual limit is.

Can you direct me to the registry path? Also to be clear the free space doesn't count towards SBS2003 SP2 75GB limit?

Thank you

The free space is substracted from edb+stm, so it's not in the 75gb limit.
The regkey I mean is the one to set the db limit to 75gb.
I normally never set this to 75gb, this way I have a small window to do the upgrade to a new server.


HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\MSExchangeIS\Server name\Private-Mailbox Store GUID

Thank you, and is free space including or excluding the event id showing space available after offline defrag?

I have 57.7 on the mailstore , 15.5 on the STM, event ID shows minimal free space after online defrag , is there way to determine the free space available after a offline defrag ?

What I am getting from this is I have 73.2 of 75gb in use?

You cannot really compare the sizes, due to the way that file systems work. The ONLY value to worry about is the one reported by Exchange, the file system value has to be ignored.

Offline defrag will only make your files smaller, it won't change anything to the actual db size that counts towards the 75 Gb limit.
If eventviewer tells you have 5gb free space in your database, an office defrag will make it about 5gb smaller (more likely 4-4,5gb)

@Lordpan that goes against everything I have heard, example is if you purge a mailbox and that mailbox size is 3gb, set to save/ 0 days, the offline defrag re-allocates that 3gb towards th free space / 75GB limit.

Please correct me if needed.

@onecare: what you say is 100% correct. But in my example, I did not purge anything and change the keep deletes mailboxes on 0 days, it was only to free disk space.
If you purge a mailbox and change the value to 0 days, the next night when exchange writes in the eventviewer how many free space he has,  you'll see that there is an extra 3Gb of free space (given that your other users didn't fill it up)
