Does anybody have any experience using Thunderbird with the Owl plugin
for connecting to Exchange OWA?

I've been thinking it might be a better option than hiri.

https://www.hiri.com/

I've been using hiri for a couple years now, but development and
support seemed to have stopped several years ago. It still works as
well as it always did, but there are years-old bugs that don't look
like they're ever going to get fixed, and there are some rather basic
features that are missing or don't work. On the pro side, the calendar
function does sync up and work pretty well. The basic mail
functionality works good enough about 80% of the time.

But, every month or two an e-mail thread gets broken and you have to
delete the account and start from scratch. The editor is also lacking
basic operations like indent, quote, code block, font/color, insert
image, and a few others. Oh, and there's no "undo" in the
editor. About once a day, my emacs muscle memory will kick in and I'll
hit ctrl-a to move the beginning of the line and then start typing
something. Poof, the entire draft is gone with no way to recover.
I've found that a viable work-around for anything at all long or
complex is to edit the message using markdown-mode in emacs, preview
the message in a browser, and then cut/paste it into hiri's editor
window. But, the OWA web UI works just as well for that...
