Error description

  • When attempting a TDP Exchange backup using release 6.1, this
    can witness the error:
        ACN5918W The mailbox history did not update successfully on
    the TSM Server.
    The backup will continue after this error.
    This error will normally occur is there are non-ascii characters
    in one of the AD entries for the Exchange information or the
    mailbox is corrupted and needs to be reset by the exchange
    administrator. Note that non-ascii characters, such as would be
    seen for international names, are allowed in the display name,
    but not unicode characters that are from a different code
    page than the one used on the system.
    To obtain the entries that would be gathered for the mailbox
    history, the following dsquery can be run on the Exchange Server
    machine:
    dsquery * domainroot -filter
    "(&(objectClass=user)(msExchHomeServerName=*/cn=*))" -attr
          mailNickname displayName homeMDB legacyExchangeDN
          msExchMailboxGuid
    Note:  The mailbox history is updated for all mailboxes for all
    storage groups, even if the storage group is not requested for
    backup.
    .
    Other symptoms that can occur are:
    When attempting a mailbox restore from the Data Protection for
    Exchange GUI "Utilities-->Mailbox Restore" menu, the following
    message is displayed:
      ACN0004E An unknown error has been detected.
    When attempting a mailbox restore" from the Data Protection for
    Exchange CLI using the "TDPEXCC RESTOREMailbox" command, the
    following message is displayed:
     ACN0151E Errors occurred while processing the request.
    .
    Another unwanted behaviour of this defect has been described
    when performing Single Mailbox Restore (SMR) to a specified
    destination mailbox:
    .
    If an MS-Exchange user name was changed after backup, the
    szDisplayName of his backup data is different from the current
    mailbox szDisplayName, although szAlias is still identical.
    TDP MS-Exchange cannot find the correct destination mailbox in
    MS-Exchange under these conditions, because of an insufficient
    search algorithm. Eventually the restore defaults to the mailbox
    of the requesting user.
    .
     Initial Impact: Medium
     Keywords:  zz61  mail box displayname NullReferenceException
    

Local fix

  • To work around this error, place the following parameter into
    the TDP Exchange configuration file (tdpexc.cfg by default).
       STOREMAILBOXInfo NO
    This will stop the mailbox history from being queried or saved.
    NOTE:  The mailbox history information is used for the
    Individual Mailbox Restore and is only needed if the mailbox has
    moved from it's original location (since it was backed up).
    If the mailbox has moved and the mailbox history information
    has not been gathered due to this work around, it will be
    necessary to manually provide the original mailbox information
    at the time of the Individual Mailbox Restore.
