Using Thunderbird on Linux Mint for Gmail and Outlook

After installing Linux Mint, one of the first applications I wanted was an email client that could manage both my Gmail and Outlook accounts in one place. I didn't want to keep several browser tabs open all the time, and I was looking for something free, reliable, and ad-free.

That's when I decided to try Mozilla Thunderbird.

Installing Thunderbird on Linux Mint

Thunderbird is available directly from the Linux Mint repositories.

Update your package list:

sudo apt update
Enter fullscreen mode Exit fullscreen mode

Install Thunderbird:

sudo apt install thunderbird
Enter fullscreen mode Exit fullscreen mode

You can launch Thunderbird from:

Menu → Internet → Thunderbird Mail

First Launch

When Thunderbird starts for the first time, it asks you to set up an email account.

You'll need:

  • Your email address
  • Your password
  • An internet connection

Thunderbird automatically detects the correct server settings for most providers.

Configuring Outlook

  1. Open Thunderbird.
  2. Click Set Up an Existing Email Account.
  3. Enter:Your name, Outlook email address,Password
  4. Click Continue.

Set Up an Existing Email Account - Thunderbird

Thunderbird automatically detects:

Incoming Server

  • Protocol: IMAP
  • Server: outlook.office365.com
  • Port: 993
  • SSL: SSL/TLS
  • Authentication: OAuth2

Outgoing Server

  • Server: smtp.office365.com
  • Port: 587
  • SSL: STARTTLS
  • Authentication: OAuth2

Click Done.

Sign in to your Microsoft account and approve access.

Your Outlook emails and folders will then begin synchronizing.

Configuring Gmail

  1. - Open Thunderbird.
  2. - Click Set Up an Existing Email Account.
  3. - Enter: Your name,Gmail address, Gmail password
  4. - Click Continue.

Thunderbird automatically detects:

Incoming Server

  • Protocol: IMAP
  • Server: imap.gmail.com
  • Port: 993
  • SSL: SSL/TLS
  • Authentication: OAuth2

Outgoing Server

  • Server: smtp.gmail.com
  • Port: 465
  • SSL: SSL/TLS
  • Authentication: OAuth2

Click Done.

A Google login page opens in your browser. Sign in and grant Thunderbird permission to access your email.

Within a few moments, your Gmail messages and folders will synchronize.

Why IMAP Matters

I highly recommend using IMAP instead of POP3.

With IMAP:

  • Emails stay synchronized across all devices.
  • Deleting an email in Thunderbird also deletes it from Gmail or Outlook.
  • Creating folders in Thunderbird syncs with the server.
  • Read and unread status remains synchronized everywhere.

To verify you're using IMAP:

Account Settings → Server Settings

You should see:

Server Type: IMAP Mail Server
Enter fullscreen mode Exit fullscreen mode

My Experience Using Thunderbird

After setting everything up, I was pleasantly surprised.

One Application for Multiple Accounts

I can manage both Gmail and Outlook from a single application instead of keeping several browser tabs open.

Completely Ad-Free Interface

Thunderbird itself does not display advertisements.

This is one of the biggest advantages for me:

  • Outlook.com displays ads in the web interface unless you subscribe to Microsoft 365.
  • Gmail may show promotional categories and sponsored content.

Thunderbird simply shows your email and folders without distractions.

Better Focus and Productivity

Because everything is in one place:

  • Email management feels cleaner.
  • Searching messages is easier.
  • Notifications are centralized.
  • I can work without opening a web browser.

Offline Access

Thunderbird can keep local copies of emails, allowing me to access older messages even when I don't have an internet connection.

Folder Synchronization Works Well

Since both my accounts use IMAP:

  • New folders appear everywhere.
  • Deleted messages sync automatically.
  • Sent emails stay synchronized.
  • Changes made in Thunderbird are reflected on the web versions of Gmail and Outlook.

Final Thoughts

Thunderbird feels like a perfect companion for Linux Mint. It is lightweight, open source, free, and provides a distraction-free email experience.

If you're a Linux Mint user who manages multiple email accounts, I highly recommend giving Thunderbird a try. It has become one of the first applications I install on a new Linux system.
