This updates my previous posts (in this thread) regarding trouble signing into my Outlook email account. My work-around of refreshing the page no longer works. I got various pop ups like "too many requests" and other error notices. A remark to the side of the failed log in attempt suggested trying a VPN or another device. Neither of those helped. I finally shut off my modem and restarted the laptop, then I was able to log in. Just putting this out there in case anyone else is having the same problem.
If anyone else has figured out a simpler solution, please post it. Thanks.
