The problem is that each copy of Thunderbird runs alone, unaware of the existence of the other copies. You could try setting up a global profile on a virtual drive that all versions access, but I have no idea how stable that would be.

Hm. So I can use syncthing for that right? And sync whole profile folder between computers.

I did not mean to offer a solution. Conceptually, a virtual drive would be a possibility, and Windows does support that capability. Having more than one PC connected at the same time could be disastrous though.

Admin edit:

Sync was delayed from the original estimate. A new status was posted in July 2023 "We don’t have a solid release date, but our objective is to have Thunderbird Sync finished in time for the next ESR release, or shortly after we switch to a monthly release schedule (we’re aiming to complete that transition to monthly by early 2024)." https://blog.thunderbird.net/2023/07/an-update-on-thunderbird-sync/
