I have O365 with Windows 10 Pro...since two weeks ago I can no longer connect to my email in Outlook. Webmail still works, so I know the password is correct. I have a 2nd user with a new laptop, same setup, that also can't. It just keeps asking for UN/PW. I've done an online repair of Office and also uninstalled and reinstalled completely.
I've also tried running the Office repair tool from Microsoft with no luck.
Anyone else experiencing this issue and have a fix?
