> We plan to launch the first phase of built-in support for Exchange, as well as Mozilla Sync, in a future Nebula point release (e.g. Thunderbird 128.X). Although these features are very close to being finished, technical obstacles prevented them from being ready today. Alex will keep you updated in his monthly Thunderbird Monthly Dev Digests.<p>> For advanced users who want to help test our initial implementation of Exchange (currently limited to Mail), we’ve hidden the option behind a preference. This Wiki page explains how to enable it. 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.<p>It ia finally coming. I really don't know what is so special about Exchange that took them all these years? There were already an extension to allow Exchange for a decade or so.
It's nice to see progress on Thunderbird after roughly a decade of stagnation and obscurity. I hope they improve the situation with DNS protocol records in terms of automatic domain configuration. I've configured them for a couple of my domains, and it seems no mail clients use said records, which is kind of silly as it seems to be one of the primary usages of subdomains or separate domains for actual mail exchange.<p>Also, glad to see the addition of Rust... might be interesting to see a revival of Servo for message display all around, since it can be more subtle than the needs for full web rendering of email.
As a long (long!) time user of Thunderbird I find these recent updates to the UI mostly annoying. I've stuck with TB because it didn't change what didn't need fixing.<p>I hope this can be configured to look like it was. Exchange and Mozilla Sync support are a welcome addition, though.
