"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

Can you increase the logging on the information store service and see if you get any more logging?

This issue may occur if a database page is corrupted. This may cause the Microsoft Joint Engine Technology (JET) database engine to stop responding.

This problem may occur when the Exchange computer’s disk subsystem is not functioning correctly. It is a good idea to run disk subsystem diagnostics to look for input/output (I/O) failures.

Option 1 (mentioned in article)
- dismount the database that is causing event ID 1025.
- To do this, right-click the database, and then click Dismount Store.
- To confirm the database corruption, run eseutil /g on the database that is causing event ID 1025.
- If the database indicates corruption, run eseutil /d to defragment the database.
- Execute eseutil /g again to confirm whether the database is consistent.
- The Eseutil utility should display Integrity check successful.
- In Exchange System Manager, right-click the database, and then click Mount Store.

Option 2 (not mentioned any article - actually a work around)
- create new store and move all mailboxes from current store to new store.

Sounds good!!

Please remember, this is a workaround. So if you face problem with other mailbox stores, on older location - I feel once you should try following "Option 1".
