<p>To store your emails, feeds, and settings across different working sessions, turn on the [[Thunderbird Email Client|persistent_storage/configure#thunderbird]] feature of the Persistent Storage.</p>
If the automatic configuration succeeds, you might have to specify which protocol to use to connect to your email provider, either **IMAP** or **POP**.
- With **IMAP**, *Thunderbird* constantly synchronizes with the server and displays the emails and folders that are currently stored on the server. IMAP is better suited if you access your emails from different operating systems.
