To fix the issue of Gmail IMAP not being verified, follow these steps:
Enable IMAP in Gmail settings: Go to Gmail settings, click on the "Forwarding and POP/IMAP" tab, select the "Enable IMAP" option, and click on "Save Changes".
Double-check IMAP settings: Make sure you have entered the correct IMAP settings in your email client, including the incoming mail server (imap.gmail.com), port (993), SSL/TLS encryption, and your Gmail account credentials.
Disable antivirus or firewall: Temporarily disable any antivirus or firewall software on your computer, as they may interfere with the IMAP verification process.
Generate an "App Password": If you have enabled two-factor authentication (2FA) for your Gmail account, generate an "App Password" specifically for your email client and use it instead of your regular Gmail password.
Clear cache and cookies: Clear the cache and cookies of your web browser or email client, as they may cause conflicts with the IMAP verification process.
Check Google account security settings: Make sure there are no suspicious activities or security alerts related to your Gmail account. If there are any, resolve them before attempting to verify IMAP.
Contact Google Support: If the issue persists, contact Google Support for further assistance or visit the Gmail Help Center for troubleshooting guides.
