I'm using Windows Live Mail as my email client under Windows 10 

In anticipation of upgrading to Outlook.com, I'm following the Export advice offered in https://support.microsoft.com/en-ie/kb/980534.

Having selected "File/Export" and confirming "Microsoft Exchange" I get an error "There is no email program associated to perform the requested action. Please instal . . . "

What exactly is meant by "the requested action"? When I go to the Program association window, I cannot determine what "actions" I should be associating or with what program/App. (It's hardly "email" since this is obviously installed and demonstrably working since it was WLF that generated the error in the first place)

Any help getting over this obstacle will be appreciated.
