Exchange 2003 Std store dismounted

I got a problem with one of the clients.  They have Exch 2003 Std 75GB limit.  They run out of space all the time, the VP has 12GB mailbox and never deletes anything.  They are waiting for a approval to migrate to Exch2010.

What could be a temp solution?  Does that exchange going thru that maintenance procedure nightly and dismounts or whenever reaches the space?  Would that depend on logs as well?  Are the logs part of the store also?

Please advice..

No logs are not part of the store.

A temp solution would be to get people to delete stuff, then set your deleted item retention to 0, then set your IS maintenance to run always.

Restart the msExchangeIS service after doing the above and then exchange online defrag will run and will flush all the deleted items out of the DB. It should result in a nice 1221 event giving you loads of White space back, then you can change your online maintenance window back.

Also consider upgrading to exchange 2003 enterprise, which will be quicker than migrating / transitioning to E2k10

By default, Exchange will check the logical size of the database once a day. You can change the time of day that this occurs with a registry setting. See here:
http://www.msexchange.org/tutorials/Explaining-Database-size-limit-changes-Exchange-2003-Service-Pack-2.html

At least this will dismount the database at a time of your choosing when you could then schedule a script to re-mount the database? Here is a possible script : http://exchange.mvps.org/E2K3/mount%20a%20store%20via%20cmd.htm

Note - I've not tested this script so I don't know if it works. Ultimately though you should create an additional database (if possible) and move some mailboxes to it until Exchange 2010 can be deployed to replace the Exchange 2003 server. Until you shrink your database, it will continue to dismount on a daily basis.

Another option is to have your packrat VP migrate older things out to a PST. That way he has it but you get some space back.

Also if you already transitioning  / already ordered an enterprise or newer version with more space capabilities for the database, an alternate easy solution is:  export the emails of a few big users (example their sent folders or something big) to pst, and save that pst on the network (so it gets backed up at night) and open that pst in their outlook so the user can access the data if they need it.. You would of-course delete it out of exchange once you move it to pst.  Once your new exchange is in place.. import pst back in, and user can continue as before.. personally I would try the defrag method first to free up as much as possible first.. than look at alternatives..

I attached the image.  The retention is already set to 0.  Where is the IS maintenance settings to set to Run Always?

It's not using it.  When you delete something, it's gone with little to no hope of recovery. No consultant I know of would recommend that setting for a long term...

If you were using it, the "Keep deleted items for (days):" would be set to a number other than zero.

Got it.  This is a temp soluition until the problem resolved and Exchange migrated to 2010.

Opening PSTs over the network is not supported by MS as large PSTs tend to get corrupt

Another thing, if I decide to offlile defrag.  I believe online defrag happens nightly.  

How can I determine how much is empry 'white' space the store has and defrag would help.

I can imagine 75GB store defrag will take like all night 12 hours...

MegaNuk3Commented:
Look in the application event log for 1221 event as I mentioned earlier this will show how much space an offline defrag will reclaim

MegaNuk3Commented:
Depending on how fast your hardware is you can get anything from 4Gb-60Gb an hour during defrag.

Hmm, not too much I guess.  So the offline defrag would be useless I guess..

As for upgrading to Exchange 2003 Enterprise Edition.  Is is as easy as reinstalling option?

As for the costs... Do they still selling licenses for it?  Do I need CALs also or just server license 'upgrade'?

MegaNuk3Commented:
Stick in the CD and 'upgrade' which is like a reinstall. You should be able to buy a license off eBay no CALs required

So straight upgrade.  I guess I just need to make sure the backups are completed.

How much time would you estimate for this upgrade?  75GB store, 30 users.

I did it once.  Took me less than an hour.. server wasnt the greatest either..

Okay looks like a pretty straight forward process.  Anything should I be aware of?  Any other gotyas?

Be prepared to reinstall Exchange 2003 SP2 and any other post SP2 fixes because from what I remember it will replace all the files. It doesn't simply upgrade the the Product Key.

Also, what I heard you still need to remove some registry key files.  The Application logs still will report the DB approaching 75GB limit.  

Is that true?

not to my experience (after upgrading to enterprise)

Got it.   What about the DB limit in the registry.  If I increase that number will I get more space??
