Thunderbird 145 finally adds native Microsoft Exchange support and enables DNS over HTTPS

Thunderbird 145 has arrived, marking a substantial update for users who rely on Microsoft Exchange email. The new release introduces native access to Exchange servers through the Exchange Web Services (EWS) protocol, eliminating the need for third-party add-ons and offering seamless email integration. This update enables users to access full folder listings, synchronize messages, manage folders on both the client and server, and handle attachments within Exchange environments.

However, while email support is fully integrated, users should note that calendar and address book synchronization for Exchange accounts are not yet available and remain on Thunderbird’s development roadmap. These features are expected in future versions.

Following the protocol and platform changes, Thunderbird 145 has ended support for 32-bit Linux x86 binaries. This affects users on legacy Linux systems who may need to switch to a supported architecture. At the same time, Skype integration within the address book has been removed, following Skype’s retirement.

Building on security improvements, this version also introduces DNS over HTTPS support, giving users the option to secure their DNS queries for improved privacy. Updates to the Account Hub interface now enable manual configuration during both email and EWS account creation. The release also includes additional enhancements and various bug fixes.
