I have two specific email messages that causes the Windows 8 Mail App to crash. There is no error message but the app closes and I am taken back to the start screen. When this email message was at the top of my inbox, the Mail App would crash every time I started it. Other emails do not cause this problem. (The message contains HTML and a PDF attachment).
I tried running the Modern Apps troubleshooter and repairing/reinstalling the Mail App. However, if I click on this email message, it still causes the Mail App to close and return to the Start screen. Then, every time I try to re-open Mail from the start screen, it will "flash" showing that the problematic email is selected, then close and return to the Start screen.
The only "fix" I have found is to "Search" Mail (from the right hand panel of the start screen) for anything. Mail will then open WITHOUT the problematic email being selected, and I can resume use of the program.
I have reviewed other answers to this problem and have tried the solutions of using the troubleshooter, and repair/reinstall, to no avail.
