It seems like this problem is not related to the TB version 140 or 148, but due to a change on Microsoft side, not allowing older versions of EAS than current 16.1 version: https://office365itpros.com/2025/12/16/exchange-activesync-161/

Reading this article, I wonder if EAS is the best approach, it seems like there is a new API called "Outlook Mobile", but not sure if available for Desktop? BR Jan

Quote from above article:
"I don’t understand why Exchange Online users continue to use EAS clients when they can use Outlook Mobile."

It worked flawlessly for years till today. Now I'm getting error message 'Server does not support ActiveSync 2.5 or 14.0 (only 16.1). TbSync will not work with this ActiveSync server. Please fix it if possible!

I'm using Thunderbird 148. But this problem was showing before I finally upgraded from a much older version (I think it was 115 or so, and I used TbSync 4.7 for a long time on it without problems).

Hi,

Firstly, excellent add-on to Thunderbird. Do you know when an update will be available that supports 148.0?

I've checked https://addons.thunderbird.net/de/thunderbird/addon/tbsync/versions/?page=1#version-4.16 and this only goes upto 140.

Stay on ESR.

One of the most important add-ons.
If it doesn't seem to work for TB 143, you just have to increase the value 140 to 145 in manifest.json, and then it works again.

Does not seem to support version 140.4.0esr. (Add on running, but the configuration link is greyed out.) Review field doesn't make any sense here, so I gave it 5 - not fair to penalize

Not supported by latest release on the Release Channel - 142.0. Alas, Google-4-TbSync as well.

I know. They want us on the Release Channel, and they keep releasing new versions, but this makes it a nightmare for add-on/extension developers to keep up.

It is a great addon if it works, but it does not work with current version for many months and does not work even with ESR

Salve ho Thunderbird 1.39.0 non vedo ancora l'aggiornamento a Tb sync, quando sarà possibile? Eventualmente un"alternativa? Grazie.

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+

Only had this add-on for a hot second (with the Exchange add-on-add-on), but I was going mad trying to sync a professional 365 calendar where admins had set sharing to no details out of org. So far, it was easy to set up and did exactly what I wanted. <3

Wenn es funktioniert dann sehr gut, aber ab Thunderbird-Version 136.0 funktioniert es wieder nicht!
TB-Sync Version 4.11

Nachtrag vom 2025-03-19:
Es funktioniert wieder, daher wieder 5*. Danke für die schnelle Reaktion!

Me too it started to fail for the last weeks. Always causes "not responding" trying to dismiss reminders. Will have to uninstall.

Keeping up with Microsoft has become difficult. We will remove support for all Microsoft services altogether, to not set wrong expectations to our users. Thanks for your feedback.

Always causes "not responding" when syncing, and can't not sync in tray.
