Thunderbird:Exchange

Warning: Exchange support in Thunderbird is still under development i.e. pre-beta! For thrill seekers only i.e. folks who can backup and restore their Thunderbird data (email, contacts, etc) should there be issues with early support of Exchange.

.

For advanced users who want to help test our initial implementation of Exchange (currently limited to Mail), we’ve hidden the option behind a Thunderbird preference which you will change using the Config Editor . To enable it, please follow these instructions:

• Click ≡ > Settings > General
• Scroll down to the bottom and click Config Editor....
• The Advanced Preferences tab will open. Search for the string *experimental.mail.ews.enabled*
• Click the Toggle icon, , on the right until True is displayed.

While we definitely welcome your testing and feedback, please keep in mind this feature is currently experimental, and you may run into unexpected behavior or errors.
