Once you have everything in place, you can move on to the installation and configuration process of syncing Outlook Online to Mozilla Thunderbird. With Thunderbird, you can enjoy a unified email experience by managing all your emails, contacts, and calendars in one place.

Step 1: Install Mozilla Thunderbird

To begin the synchronization process, the first step is to install Mozilla Thunderbird on your computer. Follow these simple steps to get Thunderbird up and running:

Go to the official Mozilla Thunderbird website (www.mozilla.org/thunderbird/) and click on the download button.
Choose the appropriate version of Thunderbird for your operating system (Windows, macOS, or Linux) and click on the download link. The installation file will start downloading.
Once the download is complete, locate the installation file and double-click on it to launch the Thunderbird setup wizard.
Follow the on-screen instructions to complete the installation process. You can choose the default installation settings or customize them according to your preferences.
Once the installation is finished, Thunderbird will open automatically.

Congratulations, you have successfully installed Thunderbird on your computer. Now, it’s time to set up your email account and configure it to sync with Outlook Online. Proceed to the next step to get started.

Step 2: Open Thunderbird and Set Up an Account

After installing Mozilla Thunderbird, it’s time to open the application and set up your email account. Follow these steps to add your Outlook Online account to Thunderbird:

Launch Thunderbird by clicking on its icon on your desktop or finding it in your applications folder.
Once Thunderbird opens, you will see the Welcome to Thunderbird window. Click on the “Skip this and use my existing email” button.
In the Mail Account Setup window, enter your name, email address, and password in the respective fields. Click on the “Continue” button.
Thunderbird will attempt to automatically configure your account settings. If it fails, select the Manual Config button and choose the appropriate account type, which is “IMAP” for Outlook Online.
Enter the server settings for your Outlook Online account. The incoming server should be set to “imap-mail.outlook.com” and the port should be “993”. The outgoing server should be set to “smtp-mail.outlook.com” and the port should be “587”. Choose “SSL/TLS” as the encryption method for both servers.
Click on the “Re-test” button to ensure that Thunderbird can connect to your Outlook Online account successfully. If the test is successful, click on the “Done” button to complete the setup.

Now, Thunderbird is configured to access your Outlook Online account. In the next step, we will configure Outlook Online for IMAP access to enable synchronization with Thunderbird.

Step 3: Configure Outlook Online for IMAP Access

In order to synchronize your Outlook Online account with Mozilla Thunderbird, you need to enable IMAP access in your Outlook Online account settings. Follow these steps to configure Outlook Online for IMAP access:

Open a web browser and sign in to your Outlook Online account.

By enabling IMAP access, you allow Thunderbird to establish a secure connection with the Outlook Online server and synchronize your emails across both platforms. This ensures that any actions taken within Thunderbird, such as marking emails as read or deleting them, will be reflected in your Outlook Online account as well.

Once you have successfully configured Outlook Online for IMAP access, you can proceed to the next step to add your Outlook Online account to Thunderbird and start the synchronization process.

From the drop-down menu, select “Options” or “Preferences”.
In the Options or Preferences window, navigate to the “Account Settings” tab.
Click on the “Account Actions” button and select “Add Mail Account”.
A new window will appear. Enter your name, email address, and password in the respective fields. Click on the “Continue” button.
Thunderbird will attempt to automatically configure your Outlook Online account settings. If it fails, choose the Manual Config button and enter the following settings:

By default, Thunderbird will sync your inbox and other essential folders. However, if you want to sync additional folders, right-click on your Outlook Online account and select “Subscribe”.
A window will appear displaying all the available folders in your Outlook Online account. Check the boxes next to the folders you want to sync with Thunderbird.
