Mailbox move - "TooManyMissingItemsPermanentException"

I'm performing a migration from Exchange 2007 to 2013, and have got to the stage of moving mailboxes across to the new server.  The first few mailboxes I migrated transferred across with no problems, but I've encountered one which fails with the error "TooManyMissingItemsPermanentException":

The post by Maciej Korman at suggests that changing the ContentVerificationMissingItemThreshold parameter in the "C:\Program Files\Microsoft\Exchange Server\V15\Bin\MsExchangeMailboxReplication.exe.config" file might do the trick, but I wasn't able to make this work, nor was I able to find any documentation on this.

Any ideas how I might proceed, please?

I've found out how to identify the items it has a problem with.  In the Exchange Management Shell, type:

get-moverequest -identity <user's identity> |get-moverequeststatistics -includereport |fl

That'll tell you where the problematic items are in the user's folder hierarchy.  They can then be deleted before trying again with the move.
You can specify the # for skipped corrupted items.
More Options/Bad Item Limit available in the Migration Console should help you.

The Bad Item Limit can be picked from the migration report of your failed mailbox.

Hi pcmghouse,

It seems to be making a distinction between "missing items" and "bad items".  I've tried setting the "bad items" limit to (for example) 100, but actually it's reporting that it hasn't come across anything that's defined as a "bad item" - you can see on my screenshot that it says "BadItemsEncountered: 0".
