Please could anyone help me with my outlook email sign in, Since upgrading to win 10 every time i open outlook my email address has .co.uk at the end, when it should be .com i don't know how or why it has changed. I have tried editing my account email address but there is no sign of the .co.uk address showing. so how do i change it to the correct address its now become annoying. I would appreciate any help. thanks.
