Thunderbird 145 has been released with full native support for Microsoft Exchange email via the Exchange Web Services (EWS) protocol.
This means that Thunderbird users in Microsoft Exchange environments (e.g., Microsoft 365, Office 365) no longer need third-party add-ons and benefit from seamless message synchronization and folder management locally and on the server.
Migrating from Outlook to Thunderbird is also easier, as Mozilla's email client automatically detects the settings and uses Microsoft’s OAuth2 authorization protocol.
“Until now, Thunderbird users in Exchange-hosted environments often relied on IMAP/POP protocols or third-party extensions,” reads Thunderbird’s announcement.
“With full native Exchange support for email, Thunderbird now works more seamlessly in Exchange environments, including full folder listings, message synchronization, folder management both locally and on the server, attachment handling, and more.”
Thunderbird is a free, open-source email application developed by Mozilla, and Microsoft Exchange is an email and collaboration server broadly used by businesses to handle communications, calendars, and contacts.
Typically, organizations either use Outlook as the email client app to connect to an Exchange server or the Microsoft 365 cloud service. However, any app with EWS support, now including Thunderbird, can connect to it.
To move from Outlook to Thunderbird, users have to add the account in version 145 or later of the email client, head to Account Hub > Exchange/Exchange Web Services, and let the application guide them through the rest of the process.
