Fortunately, there are several solutions you can try to resolve this problem. In this article, we'll explore seven effective methods to fix the ‘530 Authentication Required’ error in Outlook.

1. Check Your Account Settings

2. Enable SMTP Authentication

If SMTP authentication is not enabled in your email client, it can cause the ‘530 Authentication Required’ error. To fix this, navigate to your account settings in Outlook and make sure SMTP authentication is turned on.

3. Use the Correct Port and Encryption

Another common reason for this error is using the wrong port or encryption method. Typically, you should use port 587 for TLS/STARTTLS encryption or port 465 for SSL/TLS encryption. Check with your email provider to confirm the correct port and encryption method.

4. Update Your Password

If you've recently changed your email password but haven't updated it in Outlook, this can cause authentication issues. Make sure to update your password in Outlook's account settings.

5. Check Your Firewall and Antivirus Settings

Sometimes, firewall or antivirus software can block Outlook from authenticating properly. Temporarily disable these programs and try sending an email again to see if this resolves the issue.

6. Contact Your Email Provider

If none of the above solutions work, there might be an issue with your email provider's servers. Contact them to inquire about any potential problems or outages that could be causing the authentication error.

7. Re-add Your Email Account

As a last resort, you can try removing and re-adding your email account to Outlook. This can sometimes resolve stubborn authentication issues.

In conclusion, the ‘530 Authentication Required’ error in Outlook can be frustrating, but it's usually solvable with a bit of troubleshooting. By following the steps outlined in this article, you should be able to resolve the issue and get back to sending emails without any hindrance. Remember to always keep your account settings up to date and use the correct port and encryption method to avoid such errors in the future.
