Exchange error 623 in Event Log
Posted on 2008-11-02
We are running Exchange 2003 SP2.
I noticed today that we have about 3000 messages queued for local delivery in our queues on this Exchange box.
On checking the Event Log, there is an Error 623
Information Store (6276) Storage Group 1: The version store for this instance (3) has reached its maximum size of 249Mb. 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:
Session-context ThreadId: 0x000021D8
This is followed by logs of Error 1022's
Logon Failure on database "Storage Group 1\Mailbox Store 1 (Mailserver)" - Windows 2000 account Domain\user1; mailbox /o=OU/ou=OU/cn=RECIPIENTS/cn=User1.
I have checked the server and there doesn't appear to be any storage issues, and all the SG's/mailbox stores are mounted.
