I have two desktop PCs one, this one, is Windows 7, the other is Windows 10. I also have a couple of tablets. On all the others I can receive and send emails but on this W7 I now continually get a message saying I must log in - but it then rejects my password.  I have changed the password - and this new one works OK on all the other devices, but this W7 still rejects the password.

Can someone please advise how I can reset things? Thanks, in hope!
