Are you looking to configure your Thunderbird email client to keep messages on your server after you’ve read them? This is a common requirement, especially when switching from IMAP to POP3, or when you want to access your emails from multiple devices without losing them from the server. This guide will walk you through the process of setting up Thunderbird to leave messages on the server, ensuring you don’t lose important emails and can manage your email storage effectively.
Understanding POP3 and Leaving Messages on Server
Before diving into the steps, it’s crucial to understand the difference between POP3 (Post Office Protocol version 3) and IMAP (Internet Message Access Protocol), and why leaving messages on the server is relevant.
POP3 downloads emails from the server to your local computer. By default, once downloaded, these emails are often deleted from the server, depending on your email provider’s settings and your email client configuration.
IMAP, on the other hand, synchronizes emails between your email client and the server. Changes you make in your email client (like reading, deleting, or moving emails) are reflected on the server and across all devices connected to that email account via IMAP.
The “Leave messages on server” option is specifically relevant to POP3 accounts. When enabled, Thunderbird downloads your emails but leaves a copy on the server. This can be beneficial if:
- You access your email from multiple devices using POP3: Each device can download a copy of the emails without removing them for other devices.
- You want a backup of your emails on the server: Leaving emails on the server serves as an extra layer of backup, although it’s not a substitute for proper backup solutions.
- You are transitioning from IMAP to POP3: You might want to ensure emails are not immediately removed from the server as you adjust to the POP3 setup.
However, be mindful of your email server’s storage quota. Leaving messages on the server indefinitely can lead to your mailbox becoming full. Regularly manage your server storage by deleting emails from the server when they are no longer needed.
Step-by-Step Guide to Configure Thunderbird to Leave Messages on Server (POP3)
Here’s how to configure Thunderbird to leave messages on the server when using a POP3 account.
Prerequisite: Get Your POP3 Server Settings
Before you begin, you’ll need to obtain your POP3 server settings from your email provider. This information typically includes:
- Incoming (POP3) Server: (e.g.,
pop.example.com,pop3.example.com) and port number (usually 995 with SSL or 110 without SSL). - Outgoing (SMTP) Server: (e.g.,
smtp.example.com,mail.example.com) and port number (often 465 with SSL or 587 with TLS/STARTTLS). - Username or Account Name: Usually your full email address.
- Password: Your email account password.
You can usually find this information in your email provider’s help documentation or support pages by searching for “POP3 settings”.
Creating a New POP3 Account in Thunderbird
If you are setting up a new email account in Thunderbird using POP3, follow these steps:
-
Open Thunderbird: Launch the Thunderbird application.
-
Account Setup Wizard: If it’s your first time running Thunderbird, the Account Setup wizard might appear automatically. If not, or if you want to add another account, click the “hamburger menu” (three horizontal lines) in the top right corner, then go to File > New > Existing Mail Account…

-
Enter Account Details: In the “Mail Account Setup” dialog, enter your name, email address, and password. Click Continue.
-
Configuration Options: Thunderbird will attempt to automatically configure your account. If it detects IMAP, you’ll need to manually select POP3. Click on “Manual config”.
-
Manual Configuration: In the manual configuration screen:
- Ensure the Protocol dropdown for the incoming server is set to POP3.
- Enter your Incoming Server, Port, Outgoing Server, and Port details obtained from your email provider.
- Select the appropriate SSL settings (usually SSL/TLS for incoming and STARTTLS or SSL/TLS for outgoing).
- Choose “Normal password” for Authentication.
- Enter your Username.
- Click Done.
-
Account Creation Confirmation: Thunderbird will verify your settings. Once successful, your new POP3 account will be created.
Configuring “Leave Messages on Server” Option for an Existing POP3 Account
If you already have a POP3 account set up in Thunderbird and want to enable “Leave messages on server”:
-
Access Account Settings: There are several ways to access Account Settings:
- Method 1: Click the “hamburger menu” > Options > Account Settings.
- Method 2: Go to Tools > Account Settings from the menu bar (if you have the menu bar displayed).
- Method 3: In the Folder Pane (left side of Thunderbird), right-click on your POP3 account name and select “Settings”.
-
Server Settings: In the Account Settings dialog, select your POP3 account in the left pane, and then click on “Server Settings” under your account name.
-
Leave Messages on Server: In the “Server Settings” pane, find the section labeled “Leave messages on server”.

Enable and Customize:
- Check the box next to “Leave messages on server” to enable this feature.
- Optional Settings: You can further customize how Thunderbird handles messages on the server:
- “For at most [number] days”: Check this if you want to remove messages from the server after a certain number of days. Enter the desired number of days.
- “Until I delete them”: Check this if you want messages to remain on the server until you manually delete them from Thunderbird.
-
Click OK: Once you have configured the settings to your preference, click “OK” to save the changes and close the Account Settings dialog.
Conclusion
By following these steps, you can successfully configure your Thunderbird email client to leave messages on the server when using a POP3 account. Remember to manage your server storage regularly to avoid exceeding your quota. Leaving messages on the server offers flexibility and a degree of redundancy, but proper email management practices are still essential for an efficient and organized inbox. If you encounter any issues or have further questions, consult your email provider’s support resources or the Thunderbird help documentation for more detailed assistance.
