If you are using Office 365 for your business or personal email, chances are you are familiar with Thunderbird as a popular email client. However, configuring Thunderbird to work seamlessly with Office 365 can sometimes be a bit challenging. Fortunately, with the OAuth2 protocol, you can easily set up Thunderbird to access your Office 365 account securely.
OAuth2, which stands for “Open Authorization 2.0,” is a secure protocol that allows third-party applications like Thunderbird to access your Office 365 account without needing your password. With OAuth2, you can grant Thunderbird permission to retrieve and send emails, manage calendars, and access other Office 365 services on your behalf.
Setting up Thunderbird with OAuth2 for Office 365 involves a few simple steps. First, you will need to install the necessary add-ons or extensions, such as the “ExQuilla” add-on, which adds Exchange Server capabilities to Thunderbird. Once you have installed the add-on, you will need to configure it to use OAuth2 authentication instead of the traditional username and password method.
With OAuth2, Thunderbird will redirect you to the Office 365 login page, where you can securely enter your credentials. Once you have successfully authenticated, Thunderbird will receive an access token that allows it to access your Office 365 account. This access token is securely stored on your device, ensuring that your Office 365 account remains protected.
