Using Classic Outlook on Windows for personal email, calendar, and contact management
Hello,
What is the exact error message you receive when adding your Yahoo email account to the Outlook (Classic) Mail application?
Did you generate an 'App password' for the Yahoo email account instead of using the regular password?
To do that, open Yahoo Mail on the website and go to the Security Settings page.
- Under "External connections," click Create app password.
- Enter your app's name in the text field. (App name - Outlook Desktop)
- Click Generate password.
- Use the one-time password to log in to your Outlook Desktop app.
- Click Done.
Use this One-time password to sign in to the Outlook desktop app.
To set this account as Primary-
Once the account has been added to the Outlook app, go to File > Info> Account Settings > Account Settings.
Select the Yahoo email account in the list and click the "Set as default' option.
Let me know if you still need more help.
