When trying to add my outlook.com account to Outlook 2016, Outlook was continually asking for my password, and wouldn’t move any further. Clearing your Credential Cache, creating a new profile, etc., etc. where what I kept finding when researching the issue. The truth is, you may not need to do all of that.
Do you have two-factor authentication turned on in outlook.com? If so, you simply need to create a new app password for Outlook 2016. This is a simple process.
- Login to outlook.com using your browser of choice
- Click on your avatar then click on “View Microsoft Account”
- Click on “Security” then at the bottom click “more security options”
- Under “App passwords” click “Create a new app password”
Once the password has been created, enter it in to the password field when Outlook 2016 prompts you for your outlook.com password.
Hope this helps.
