Exchange 2000 stuck at 16GB
Posted on 2009-04-07
I have a SBS2000 running Exchange 2000, yesterday it hit the 16GB limit and since then I had nothing but problems with it.
I first did the registry trick and this allows the workstation to connect, I then archived 3GB off the server, but still the EDB shows 16.1GB in size, I then tried eseutil /p followed by eseutil /p with same result, I did a reboot just in case, I check the Mailboxes in ESM and this shows adding all users comes to just over 12GB (only 7 users), yet I cant get Exchange to free up the space so I can mount the server correctly as it stays at 16.1GB, hence shutting down the IS.
When I ran eseutil /p it came back with over 100 unknown errors but I managed to restored an image from yesterday to a fresh test server and it show the same errors yet the server were still working, I could use the spare test server as its almost identical minus this morning emails, but the EDB on the restored server showing 15.9GB so its a matter of minutes before I get hit with the same thing.
Would be most grateful for any help on this one urgently as I been doing this for over 8 hrs non-stop.

Try:
go into the exchange system manager (2003) and open the properties of the mailbox store, limits tab, deletion settings section.

You may also try creating a second mailbox store and moving some of the mailboxes to it, but Im not sure if you can do that in your version.
The space reported in Exchange System Manager for a user's mailbox will be vastly different to what is reported in Outlook; it can't be relied upon to give a true indication of the total size of the mailboxes.
Deleting data from a mailbox will not erase it from the Exchange stores immediately; Deleted Items retention will mean the mail remains in the store until Online Maintenance removes it.
Since the database is dismounting at 16GB, I assume this is Exchange 2000 Standard Edition, where you are limited to one mailbox store. We therefore cannot simply create a new store and Move Mailboxes, per best practice; you need to mount the database temporarily, and take action to reduce its size.
The first step is to mount the database. Add the fix defined at http://support.microsoft.com/kb/813051, which temporarily extends the maximum store size to 17GB and will allow you to mount the database.
Reduce Deleted Items retention time to 0 days, then force Online Maintenance to take place. This will zero out the database pages used by the items in the dumpster.
Finally, dismount the database and run an eseutil /d - this will perform an Offline Defrag of the database, removing the white space and bringing it back below the 16GB level.
Remove the registry entry added earlier, then re-mount the store once again.
