I had to change my Google password yesterday. Doing so apparently made Outlook repeatedly ask me for a "Netword password" (that hadn't happened ... ever?) Nothing I tried worked. (I wasn't even sure what my User name was supposed to be, since it had been years since I set up Outlook. It turns out it was my Gmail account name.)
I had assumed (correctly, it turns out) that the password being requested was my the Google password for my ancient Gmail account. The one that I set yesterday.
However, Outlook refused to take it or any other password.
(By the way, the Account settings told me the user name that Outlook had been requesting the password for--my full Gmail account name.)
After clicking Repair..., I entered what I knew was the correct new password (that Outlook had been rejecting all morning). I clicked Next and Google "repaired" whatever problem Outlook had been having. I was able to send and receive email after this.
<Google: This is no way to run a railroad.> But somehow it worked. I did not expect it to.
So this isn't as much a question as a comment that I hope will help people or that people will reply to in order to clarify what the problem really was.
(The suggestion of changing settings in Control panel for sharing did not work for me.)
