All mails being disappeared in google chrome after 15 days

That's frustrating!

It's possible that the emails are being deleted by Google Chrome's built-in email client, Google Mail (Gmail) or by a third-party extension. Here are some potential solutions to help you recover your emails:

  1. Check your Gmail settings: Ensure that your Gmail account is set to keep emails for at least 30 days. You can do this by following these steps:
    • Sign in to your Gmail account.
    • Click on the gear icon in the upper right corner.
    • Select "See all settings."
    • Go to the "Filters and Blocked Addresses" tab.
    • Look for the "Delete messages older than" option and set it to a higher value (e.g., 30 days).
    • Click "Save Changes."
  2. Check for extensions: Disable any email-related extensions in Chrome to see if they're causing the issue. You can do this by:
    • Clicking on the three vertical dots in the upper right corner of Chrome.
    • Selecting "More tools" > "Extensions."
    • Looking for email-related extensions (e.g., "Email Checker," "Email Manager").
    • Clicking the "Disable" button next to each extension.
  3. Clear Chrome's email cache: Clearing Chrome's email cache might help resolve the issue. You can do this by:
    • Pressing Ctrl + Shift + Delete (Windows/Linux) or Command + Shift + Delete (Mac) to open the Chrome settings.
    • Selecting "Cookies and other site data" and "Cached images and files."
    • Clicking "Clear data."
  4. Check for conflicts with other apps: If you're using other email clients or apps that integrate with Gmail, try closing them or disabling their integration with Gmail to see if it resolves the issue.
  5. Contact Google Support: If none of the above steps work, you can contact Google Support for further assistance. They may be able to help you recover your emails or provide additional troubleshooting steps.

Remember to regularly back up your emails to prevent data loss in the future. You can use Google Takeout to export your Gmail data or set up a third-party email backup service.
