Hotmail-Oauth-2-Authentication-Error

If you're experiencing an OAuth 2.0 authentication error with Hotmail, it usually points to issues with authentication protocols or incorrect configurations. Here are some steps that might help resolve the issue:

1. Use an App Password If you have two-step verification enabled for your Microsoft account, you will need an app-specific password for your email client. Here's how to generate one:

<ul><li>Go to the Microsoft account security page.</li> <li>Enable two-step verification if it's not already turned on.</li> <li>Generate an app password and use it in place of your regular password in your email client.</li> </ul> 2. Update Your Email Client Make sure you're using an updated version of your email client that supports OAuth 2.0. Older versions may not be compatible with the latest authentication protocols. 3. Reconfigure Your Account Try removing your Hotmail account from your email client and adding it again. During the setup process, ensure you provide the necessary permissions for OAuth authentication. 4. Verify IMAP/SMTP Settings Double-check that you’re using the correct server settings: <ul><li>Incoming server (IMAP): imap-mail.outlook.com, Port: 993, Encryption: SSL/TLS.</li> <li>Outgoing server (SMTP): smtp-mail.outlook.com, Port: 587, Encryption: STARTTLS.</li> <li>Ensure that OAuth 2.0 is selected as the authentication method.</li> </ul> Know More: <a href="https://www.jagwaresoftware.com/blog/hotmail-keep-asking-for-password.html">Hotmail Keep Asking For App Password</a>
