Hello,

I'm the developer of TbSync, an ActiveSync AddOn for Thunderbird:
https://addons.mozilla.org/de/thunderbird/addon/tbsync/

The latest version is available directly at my GitHub release page (Mozilla always takes a while to review new versions):
https://github.com/jobisoft/TbSync/releases

The AddOn works with a large number of servers and services:
https://github.com/jobisoft/TbSync/w...atibility-list

However, I was not yet able to test it with OX. I do not have the resources to set up my own OX server, so I am looking here for users, who are interested and willing to test!

Feedback is appreciated.

Best regards,
John
