exporting email folder from Windows live mail to Outlook 2016 fails midway through the export .

I have been searching the forum, and have not found an answer so far. 

I am trying to move some large email folders from WLM 2012 to  Outlook 2016. Midway through the export (at about 33560 out of 37645 emails) WLM stops and restarts. I delete the folder in outlook, try again, and it fails in the same place.  I moved the emails into a different folder on WLM.  However, exporting from the new folder now, the export fails at about 14900.

  I have repaired WLM per other threads.  I have WLM offline during the operations.

I suspect a corrupt email, and if I went through all 30000+ emails, found and deleted it, life would be great.  I am hoping there is a more automated way to fix such an email, which is the purpose of the post.

I have more than 1 large folder exhibiting this behavior.

any help would be greatly appreciated.

Thanks in advance
