The error code 0X8019019A is shown when a user fails to add his Yahoo account to the Mail app due to the outdated or corrupt installation of the Mail app. Not using an App-specific but a normal Yahoo account password may also result in the error at hand.
In this guide, we will show you how to effectively fix this error so you can set up Yahoo mail.
Perform a restart of your system to rule out a temporary glitch in the system. Also, check if you can successfully access your email through a web browser using the same credentials as you are using with the Mail app. Additionally, make sure that no VPN or proxy server is being used to access the internet (VPN/proxy may work fine with the web version of Yahoo mail but may hinder the access through a mail client).
If your system is not updated to the latest build it can create incompatibility between the OS modules. Updating the Windows and Mail app of your system to the latest build may solve the problem.
The Yahoo account issue could be a result of a temporary glitch in the communication modules of the system. The glitch may get cleared if you remove and then re-add the Yahoo account to the Mail app.
You may fail to add the Yahoo account to the Mail app if the installation of Mail itself is corrupt. In this scenario, resetting the Mail app to the defaults may solve the problem.
Yahoo has implemented tons of security features to its accounts. One such feature is the use of app-specific passwords for less secure apps like the Mail app. If your Yahoo username or password is not working with the Mail app, then using the App-specific password may solve the problem.
