Hi,
I followed the link above https://www.kapilarya.com/there-is-no-email-program-associated-to-perform-the-requested-action-windows-10. I started Regedit and saw that there was no entry for Outlook there. There was an entry for Hotmail instead which I deleted. I also noticed that there
was no entry for Mail in there, so after deleting the Hotmail branch the Clients\Mail folder became empty .
The default program for Email in Settings is Mail as recommended. Mail for Windows 10 is installed OK and I'm using it. Nevertheless when I try Send to from File Explorer, I'm still getting this annoying message. Is it because there's no entry for Mail in registry?
How do I restore it?
It's in the Cortana settings, it has nothing to do with email accounts. I have disabled Cortana and now the problem has been solved.
On Windows 10, go to Settings, Cortana, Permissions & History, Manage the information Cortana can access from this device. Turn off Contact, email, calendar & communications history.
