Troubleshooting & FAQ

Frequently Asked Questions

What IMAP port and security settings should I use?

For almost all modern mail providers (Gmail, Yahoo, Outlook.com, Zoho, cPanel), use Port 993 with SSL/TLS encryption. If your corporate mail server uses non-SSL, use Port 143 with STARTTLS.

Do I need to generate an App Password for Gmail or Yahoo?

Yes. Due to modern two-factor authentication (2FA) security policies enforced by Google, Yahoo, and Microsoft, you should generate a dedicated 16-character App Password from your provider's security portal.

How can I open the exported PST file in Outlook?

Open Microsoft Outlook, click File > Open & Export > Open Outlook Data File (.pst), browse to the exported PST file on your local disk, and click OK. The entire folder structure appears instantly in Outlook's navigation pane.

Can I save IMAP emails to an external USB hard drive?

Yes! During Step 4, simply browse to your connected external USB drive or network attached storage (NAS) folder as the target output path.
