Hello !
To synch a calendar with thunderbird (version 128.1.1esr) the server adress https://mail2/Calendar/Calendar/ has tu be user.
This works fine.
But I can not synch another calendar with the same server adress although using the correct credentials for the second user.
It’s deactivated and I guess because it is the identical server adress.
Is there another adress I can use?
Thx !
Matthias
