OUTLOOK 0x800CCC13 ERROR WITH WINDOWS 10

This error is absolutely infuriating when sending email via Outlook in Windows 10, in my case with an old BT Connect account. The solution was to run a Command Prompt (Admin) from the right-click of the Start Menu, and then type “sfc /scannow” in the dos box.

Emails then started sending straight away, so god only knows what caused it but it seems to be fixed at last.
