I was sending a file from my laptop to my phone so I could print it. Had the windat issue so I first deleted the newly downloaded windat file opener app from my Android phone. That didn't make a difference. Then I deleted myself from the autofill application in Outlook 2013 on my laptop and that worked.

Manually type-in the recipients email address into the 'To' portion of the email, then send the email.
