Considering so many companies have adopted Microsoft Exchange/Outlook365 and their IT departments have locked out other communication protocols, are there any plans to address this in Thunderbird? Right now a lot of us can't use it because of this limitation. The only solutions so far appear to be Owl (for purchase) or DavMail (which requires a separate OpenJDK 8 installation). This is a fundamental need in Thunderbird rather than a third party add-on. I like the look of Thunderbird but, alas, am not able to use it.

Interesting, but there's no link to download the pre-beta version.

I have updated the wiki to point to the main download page.

Well, I've installed the daily build a few times and it still can't connect. If I'm going to pay for an add-on to get Thunderbird to work correctly, I might as well pay for a commercial mail client that works.
