You've already addressed my first thought, AV. Some random comments:
No one with a 10 GB mailbox should expect good performance from Outlook, particularly in cached Exchange mode. People who insist on doing this should at least try to keep folders under 5000 items, particularly the built-in ones such as Inbox and Calendar. It's been reported that custom views also contribute to slow performance with Outlook and large mailboxes.
It's not recommended to do an offline defrag of the Exchange databases unless you have diagnosed a problem that calls for that, or unless you can reclaim 30% of the space in the database. In other words, unless your 73 GB database has 22 GB of slack, don't defragment it. (See event 1221 in your application log for the amount of slack, or free, space in the databases).
I would also resist any temptation to tinker with Exchange's memory usage. This is much more likely to cause more problems than to help. The RAM figure you quote for store.exe is not out of line with what I'd expect, and Exchange will give up some RAM if something else needs it.
From your post, you have not ruled in Exchange as the cause, or ruled outother issues. This could be another app on the server - in Task Manager, what are you showing for RAM and typical CPU usage? An app causing high CPU usage could as easily be the cause of performance issues. You could also have a network hardware or congestion issue.
I'd start by looking at resource usage, and see if there are any errors in the logs. Look at page file configuration, free space on all volumes, and try to get some idea how much network traffic is going on.

Hello all,
I have an sbs2003 server that as of late has been experiencing major
perofrmance issues. The server itself runs very few programs (qb
database server, symantec endpoint server). There are about 40 user
mailboxes,some over 10g (I know thats not good, but unfortuntely I
cannot change that :( )
Over the last two weeks users have complained about slow performance
of quickbooks and extremely poor performance of OWA. The priv1
database is about 73gb.
I know there are alot of recommendations for exchange memory uses but
they do not always fall into the sbs realm. Is there anything I can do
to get my server back into optimal form? I have uninstalled the
antivirus software temporarily, and I tried to do an offline defrag of
the exchange db, but i keep running into a jcb.dll error.
Any and all help is much appreciated.
The server is about 5 months old, single quad core, 4g of ram and a
raid5 with tons of unused space. Right now the store.exe process is at
655mb
Thank you
Trent
