What should I do about it?

The exchange server is running under Vmware ESX 3.5.  There are about 75 Mailboxs.  Database size is about 35 Gigs.

    as long as the server is running i would not do anything too drastic.

    i would
    1.  make certain you have a good backup
    2.  run isinteg against the database and i would use the /fix switch.

    i would not
    run eseutil /p as the information store is mounting which means the IS is not in that bad a shape.

    In the Event ID link, they suggest to move the mailbox in a new store.  Is it safe to do this live without any downtime?  

    What will the command isinteg /fix do?

    moving the mailboxes to a different server is not a bad call.
    it probalby has less risk than anything else.
    there is downtime for that user while thier mailbox in actually being moved, but only for that user.

    isinteg repairs minor corruption in the mail database.

    I think you misunderstand my question.  I only have 1 Exchange server.  So I will not be moving the mailbox to a different Exchange server.  I will be moving it to the same server but to an other store.  Will there still be downtime for the mailbox that is being move?

    I will move the mailbox to an other store.  By the way, I tested when moving the mailbox to an other store, the mailbox is still available in outlook.  I test it in my test environment.

    Thank you,
