User Interface

Thunderbird wins the category for price because it’s essentially free. However, MS Outlook has tons of other and better features. For example, you can subscribe to Outlook starting at $6.99 per month. The paid version comes with 1 TB storage and full versions of the MS Office apps.

Both clients are efficient in their purpose. To manage multiple emails or cross-platform emails, Thunderbird is a better choice. MS Office is superior if you’re only going to use Outlook.

Thunderbird also has the feature to include Outlook in its emails.

Final Words

Both email services, Outlook and Thunderbird, are excellent at their purpose. You can choose between one based on your requirements.

Thunderbird is free, has a simple UI, is easy to handle, supports cross-platform or multi-manage emails, and has good security options.

MS Outlook doesn’t have multi-platform support. The full version needs to be paid for. But it has a superior and super convenient UI. The security that Microsoft offers is top-notch.

Switching from MS Outlook to Thunderbird isn’t a problem because it already has support for MS Outlook.
