When you answered the security prompt with “Turn off access”, you can turn it back on by going into your Yahoo Security settings. Method 1: Allow apps that use less secure sign-in Turning off less secure access for your Yahoo account will result in password prompts and error 0x800CCC92 in Outlook. To resolve this, you can either re-allow the less secure sign-in methods for your Yahoo account or turn on Two-Step Verification. The more secure sign-in method that is being referred to in the security prompt by Yahoo is the use of OAuth 2.0 instead of the Basic Authentication method that is being used now.Ĭurrently, Outlook doesn’t support OAuth for Yahoo accounts so you’ll end up getting repeated password prompts from Yahoo after you set your account to not allow less secure sign-in methods. How can I re-enable Outlook to collect my email again, preferably by using the more secure sign-in method the original prompt was referring to? I know my username and password are correct as they still work when I try to login to Yahoo Mail in my browser. This sounded like a good thing to do, but now I constantly get prompted for my username and password in Outlook and it no longer downloads my emails and I can’t send anymore either. I got prompted by Yahoo to disable access for apps that use less secure sign-in methods to get my email.
