Hello,

I'm the developer of TbSync, an ActiveSync AddOn for Thunderbird:


The latest version is available directly at my GitHub release page (Mozilla always takes a while to review new versions):
[Thunderbird Add-On] Central user interface to manage cloud accounts and to synchronize their contact, task and calendar information with Thunderbird - jobisoft/TbSync


The AddOn works with a large number of servers and services:
[Thunderbird Add-On] Central user interface to manage cloud accounts and to synchronize their contact, task and calendar information with Thunderbird - jobisoft/TbSync


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
