The results show a strange icon, even though Win 8.1 is set with Live Mail as default for .eml files.  When I try to open one of the emails by selecting or reselecting Live Mail in the drop down options of "Open", "Open with" or Properties, it doesn't work.  However, if I go to Control Panel/Programs/Windows Essentials/Repair all Window Essential programs, and run it, the problem is temporarily fixed.  Then when I run search, the results display an envelope icon, and when I click on it, the email opens.

This does not reoccur each time I restart the PC, just irregularly.

Any help most welcome.

Thanks.
