New-MailboxExportRequest Error RRS feed

  • Question

  • I've been working with Export of Mailboxes into PST files since exmerge days in Win2003, and I consider myself to know what to expect.

    I recently came across an Exchange 2016 and created a routine to Export mailboxes (not many) to a share with a scheduled job.

    This is the Error:    1. The second (and consecutive) runs always Failes.   2. The PST-file size seem to grow for no reason, sometimes x1.5, x2 , x3 times,  even if running with just 5 minutes apart.
     (but, when opening the PST-file all is ok inside, not more there, just what is expected)

    Same box, Export to Same PST File, several of times, works great on Ex2010 and Ex2013 

    (I have done this thousands of times with Exchange 2010 and 2013, always perfect result.   New items are being added, file size increasing only little each day, if new items are added.   The export job hardly never fails.

    Expected behaviour:  I am expecting the Export to add new items from the mailbox if the box have any, I expect the files-size remain unchanged if no new items are to be added, I expect the export job to finish with "Completed"

    If looking into the error report it indicates "TooManyMissingItemsPermanentException" but bad items count is still 0
    It never fails on first run, exporting to a file that doesn't exists.
    Setting up a test mailbox "NEW", add some mails by sending them to the box, then doing the export, still same problem.
    the box is not broken. something is wrong with the New-MailboxExportRequest function.

    I have two Export-reports ready if someone like to see, same box, with 5 min apart

  • Hi Kjell,

    How do you create the routine export task? Did you remove the first completed request before starting the second one? Microsoft Exchange automatically generates up to 10 unique names for a mailbox export request. To create more than 10 requests for a mailbox, you need to specify a unique name when creating a new export request, or remove the completed request. For your reference:

    New-MailboxExportRequest

    To uncover the issue, you can run the following command to go through all items one by one and and see what kind of problems are users having in their mailboxes.

    Get-MailboxExportRequest | Get-MailboxExportRequestStatistics -IncludeReport | fl


    Probable scenario here was that Outlook client failed to properly notify mailbox about deleted items so those items got somehow in weird state and are no longer needed. You can try the following command to ignore the problem and let Exchange ignore those items by running following commands. When the BadItemLimit is larger than 51, you need to use the AcceptLargeDataLoss switch.

    Get-MailboxExportRequest | Set-MailboxExportRequest -BadItemLimit 500  -AcceptLargeDataLoss

  • Hi Dawn Zhou

    Thanks for taking your time to look at this

    Yes, I am removing all old Export-request immediately after completed or Failed, unless I want to look at the report first.

    As I mentioned, I do have many years experience with this routine.
    Smaller organisations finds the BackupExec tool way to expensive, and we have had many years good experience using a script and simply exporting the mailboxes (merging) each night to a share on another server, including two events of crypto-attacks where we could restore all mailboxes with not data-loss within hours.

    I am well familiar with several ways to script and code C# so I can easily create routines for exporting mailboxes, remove export-request, move one mailbox each night in order to overcome the "merge" effect.

    I can do another test with setting -BadItemLimit 500 and -AcceptLargeDataLoss and return with the outcome.

    Rgds

  • I believe using baditemlimit will resolve your issue.

    We faced the same issue with enterprise vault shortcuts and every time it was getting resolved with baditemlimit.

    Second solution is modifying ContentVerificationMissingItemThreshold setting in MsExchangeMailboxReplication.exe.config file which we don't prefer to modify.

  • Hi, I have just completed a test-run as per your suggestions, adding -BaditemLimit 500 -AcceptLargeDataLoss to the MailboxExportRequest-command.

    I ran this several times for the same Mailbox, with just few minutes between, first time to a non-existing PST-file, and then towards the same file as the previous execution created/updated.

    And the result was interesting.

    The job now finishes really fast, same time It took to run it the first time, the job result is "Completed" instead of "Failed"; this is the positive effect

    But the PST file size is still growing, for each time I execute this towards the same PST file. 
    1= 11673KB  2= 22337KB  3= 32753KB  4= 43665,  5= 54081   and this indicates something is wrong in there.

    Using -BadItemLimit is not a solution, there are nothing indicating that there are real bad items as the first execution always comes out "Completed"

    When opening the PST files after 5 executions with Outlook reveals that the content is still just 1 set of the mailbox, nothing missing, nothing doubled.

  • Hi,

    Thanks for detailed description.

    Did you try to run the following command? Please run it with -IncludeReport switch to get additional information for further troubleshooting.

    Get-MailboxExportRequest | Get-MailboxExportRequestStatistics -IncludeReport | fl

  • Hello!

    Do you have any solution? I try BadItemLimit, ExcludeDimster, ExcludeFolder (junkitem, sync error) keys - it's not working for me.

  • Kjell,

    I know from working with MAPI for a very long time that PST files are not the most efficient data store.  If you are simply having the export reconnect to the same PST file each time, this alone can be the reason for the increases in size each time.

    Its likely not an issue of your configuration or setup, but inherent to how accessing PST work.  I know you stated that prior versions didn't seem to do this, but i suspect they did, but maybe in very small amounts.  

    Exchange 2016 is likely also using a newer format of the PST file that supports Outlook 2013 and later.  When Outlook 2013 was released, a new PST format was also released to support the "date slider" for OST files.  
    I suspect that Exchange is using this newer format for compatibilty (or simply just because of newer code) and so each new open and processing causes increases for temp data usage and such.

    if you are reusing the same PST file, have you tried a different pattern that recreates the PST file each time, just a test and comparison?

    also, would an alternative to New-MailboxExportRequest be viable?  Priasoft has just released a new tool called Super-ExMerge that has attempted to modernize the old exmerge tool.  It's powershell based and very high performing.
    If you're interested, here's the link:  https://www.priasoft.com/super-exmerge/
