The developer won't be happy about this, but to test compatibility with Thunderbird v139, I edited the "manifest.json" file in the *.xpi file (in the ActiveSync extension *.xpi file, too) to reflect a max version of 139.*.

It works! Beautifully! So, I don't think it will be difficult to make it compatible with v139+
