  • Cleaning Database after move mailbox

    Hi,
    My Exchange server stopped getting mail.
    I think it's b/c the disk run out of space
    I'm trying to move mailboxes from the first storage group to a new storage group on a new disk.

    The problem is that once the mailbox are moved - the original database remain the same size....

    Any idea how to clean it ?

    Thanks,

    Dani

    That's to be expected. The physical file size won't change even if it's an empty database. If you've moved all of the mailboxes to a new mailbox store then simply delete the original mailbox store.

      If you do an offline defrag of the database, the database will shrink to the used data only.
      Keep in mind that before you do this, you have to make sure that the data is backupped.

        An offline defrag is a waste of time. Just move everything out and then drop the original. Zero risk, zero downtime.

          If it is the first store then you should not delete the store without moving the SMTP, System Attendant and System Mailbox. You cant directly move those mail box, for that you have to change the system attributes to move the system mailbox, for which you can follow the procedure from the KB article below.

            First post and inaccurate with it.
            You do not have to change the system attributes to move the system mailboxes. After dropping the first mailbox store, simply restart the information store service. Exchange will recreate the system mailboxes automatically.

            I have lost count of the number of times that I have recreated the original store and not once have I had to do anything to the system mailboxes. Exchange deals with that on its own.
