Using Classic Outlook on Windows for personal email, calendar, and contact management
Hi @John S
I understand that you can still send emails from your Yahoo account in Outlook 2013, but receiving messages now results in error 0x80004005.
Since Outlook 2013 may require a Yahoo app password, please generate a new one from Yahoo Account Security > Manage app passwords, select Outlook Desktop, and then replace the current password in your Outlook account settings.
If the issue continues, please check whether new messages are available when you sign in to Yahoo Mail through a browser. If they appear there, create a new Outlook profile through Control Panel > Mail > Show Profiles > Add, configure the Yahoo account again, and check whether Outlook can receive messages in the new profile.
Please let us know the result. This will help determine whether the issue is related to Yahoo authentication or the existing Outlook profile.
If the answer is helpful, please click "Yes". If you have extra questions about this answer, please click "Comment".
