In about half the emails that my mom tries to forward with a photo she gets an error message- One or more of the pictures in this message could not be found. When you send this message these pictures will not be included. Are you sure that you want to send this message? I have tried various solutions including: (not in this order)

options > mail > compose > convert messages to photo emails when adding photos (Both checking and unchecking the box)

repairing Windows Essentials

removing and reloading Windows Essentials

This was not a huge issue until we recently had to factory restore the computer. Has there been a solution to this error message other than a very long process in which to forward the email by saving or as an attachment? I tried to explain the long route that I have seen other people using but it's too complicated for her. Any suggestions would be greatly appreciated.
