Scotty, my outlook mailbox has stopped worked. It began about a week ago when it stopped on an intermittent basis. I haven’t been able to get it going since yesterday. In between, I’ve been logging on to my gmail account on the laptop, plus rebooting but nothing seems to work. Not critical since I have my other devices but very inconvenient.

Google recently changed the way their accounts are authenticated. When adding an account, they now require you sign in using a web browser. The solution to your problem is most likely to remove the email account from Outlook then re-add it. When you re-add it, it should automatically open your browser and ask you to input your password there. After that, you shouldn't have the issues.
