    Did you check the Event Viewer ( Application logs) on your Exchange server?
    What about transaction logs, if they fill up the available space the store is automatically dismounted.

      Check the smtp service.
      When the SMTP service is unavailable, the Exchange store will dismount after a short periode of time.

        How large is the store?
        If you are using Exchange 2003 standard edition then there is a limit to the store and once Exchange hits that limit it will dismount the store.

        The limit is 16gb pre SP2, 18gb by default once Exchange 2003 SP2 has been installed and that can be increased to 75gb via a registry change and a restart of the Exchange services.

          Thanks for interest to my issue.

          I am using SBS 2003. I have found my default mailbox store has .EDB (15.8 GB) + .STM (3.42 GB) = 19.22 GB database. and the physical size of this database minus its logical free space exceeds the limit of 18 GB, and database will be dismounted on a regular basis.

          so I need to change the size of my First Storage Group\Mailbox Store. But I don't know how ? Please help me..!!!

          Thanks
