Exchange 2003 Database problems
I've been having some odd problems on my Exchange 2003 SP2 server that started last week. I'm not sure what is causing this but here is a rundown of the problems:
I got this error on two of my five stores:
Event ID 623
Information Store (2936) Back Office 2: The version store for this instance (0) has reached its maximum size of 108Mb. It is likely that a long-running transaction is preventing cleanup of the version store and causing it to build up in size. Updates will be rejected until the long-running transaction has been completely committed or rolled back.
Possible long-running transaction:
SessionId: 0xBD330A20
Session-context: 0x00000000
Session-context ThreadId: 0x0000156C
Cleanup: 1
This error follows:
Event ID 9791
Cleanup of the DeliveredTo table for database 'DB PATH' was pre-empted because the database engine's version store was growing too large. 0 entries were purged.
This would be followed by this error for a variety of accounts:
Event ID 9646
Mapi session "/O=PATH/OU=PATH/cn=Recipi
and
Event ID 1022
Logon Failure on database "DB PATH" - Windows 2000 account CUNJ\gfi; mailbox /O=PATH/OU=PATH/cn=Recipie
Error: -1069
There was obviously a problem with the mailbox stores so I created two new ones and migrated the users to it. I'm still getting errors 9646 (though less of them) and also a new error this morning:
Event ID 8263
The recurring appointment expansion in mailbox USERNAME has taken too long. Some recurring appointment instances may not be visible at this time. To ensure that the calendar view is correct, please refresh the calendar view in Microsoft Outlook Web Access.
I'm at a loss. Can anyone help me determine what the root cause of these errors are and how I might be able to fix it? Users do seem to be able to operate Outlook though I have many reports of very slow performance. I would very much appreciate any help, thank you!

So far the steps above seem to have helped with most of the larger DB problems. I'm still seeing errors for having too many objects open for certain users so I'm running startup switches with Outlook to do profile and other cleanups.
