Mail.live.com certificate error

The infamous "Your connection is not private" error!

The error "Your connection is not private" or "NET::ERR_CERT_AUTHORITY_INVALID" when trying to access mail.live.com (or any other Microsoft website) is usually caused by a certificate issue. Here are some possible solutions:

  1. Check your browser's date and time settings: Ensure that your system's date and time are set correctly. An incorrect date or time can cause certificate validation issues.
  2. Clear browser cache and cookies: Clearing your browser's cache and cookies can sometimes resolve certificate issues. Try clearing your browser's cache and cookies, then try accessing mail.live.com again.
  3. Check for browser updates: Ensure that your browser is up-to-date, as updates often include security patches and certificate fixes.
  4. Try a different browser: If you're using a specific browser, try accessing mail.live.com with a different browser to see if the issue persists.
  5. Check for antivirus software interference: Some antivirus software can interfere with certificate validation. Try temporarily disabling your antivirus software and see if the issue resolves.
  6. Check for Windows updates: Ensure that your Windows operating system is up-to-date, as updates often include security patches and certificate fixes.
  7. Reset your browser's SSL/TLS settings: You can try resetting your browser's SSL/TLS settings to their default values. For example, in Google Chrome, go to Settings > Advanced > System > Open proxy settings > LAN settings > Advanced > Reset.
  8. Check for certificate revocation lists (CRLs) and online certificate status protocol (OCSP) responders: Sometimes, CRLs and OCSP responders can become outdated or unavailable, causing certificate validation issues. You can try checking the Microsoft CRL and OCSP responders to see if they're working correctly.
  9. Contact your network administrator: If you're accessing mail.live.com through a corporate network or a public Wi-Fi network, contact your network administrator to see if there are any specific settings or configurations that need to be adjusted.
  10. Try accessing mail.live.com through a different method: If you're accessing mail.live.com through a specific app or add-in, try accessing it through a different method, such as using the Outlook desktop app or accessing mail.live.com directly in your browser.

If none of these solutions work, you can try contacting Microsoft support or your browser's support team for further assistance.
