    1. It shuld be there for you to reocover, mbx may have not been marked just yet, you may have to run the clean-mailboxdatabase - http://technet.microsoft.com/en-us/library/bb124076(EXCHG.80).aspx
    2. Also, if you checlked  Do not permanently delete mailboxes and items until the store has been backed up it may have been purged
    3. Or wait.  Then you can reconnect if you wish.

    If you've made no changes to the "Keep deleted mailboxes for (days)"
    value on the mailbox database then the mailbox will remain in the
    database for 30 days. You shold be able to reconnect the mailbox to
    the original AD user or to another AD user that isn't mailbox-enabled.
     
    >I checked the "Disconnected Mailboxes" the following day and it was not there.
     
    Try running "Clean-MailboxDatabase" on all your mailbox databases and
    then check again after a while. The disconnected mailbox will only
    appear in the "Disconnected Mailboxes" view after the information stor
    discovers that the "full directory name" stored in the mailbox no
    longer has a match to any "legacyExchangeDN" property value in the AD.
    If your normal background maintenance tasks aren't running then the
    mailbox may not have been checked for a "connection" with an AD user.
     
    OTOH, someone else may have permanently removed the mailbox -- or your
    retention period isn't what you think it is (maybe it's zero, not
    thirty, days?) and the mailbox was removed by the background
    maintenance tasks.

  • Hi,

    Deleting a mailbox does not mean that it is permanently removed from the Exchange Information store database. Actually when you delete a mailbox in Microsoft Exchange server, it is disconnected  for a retention period. During this period, you can easily reconnect it.

    Read more about how to recover deleted mailbox when it is in retention period: http://support.microsoft.com/kb/274343

    Note: At the end of the retention period, the user's mailboxes are permanently removed from the Exchange server database and only a backup copy or a third party Exchange recovery tool can help you to recover these mailboxes.

    Regards,
