Wäre genial, würde TbSync mit der 2-Faktor-Authentifizierung von GMX funktionieren. So leider nicht zu gebrauchen für mich...

This review is for a previous version of the add-on (2.11). 

Um das Problem zu beheben, würde ich mich über einen Bug-Report auf der Entwickler-Seite freuen. Gibt es denn irgend ein anderes System/App/Client/Programm, das mit CalDAV/CardDAV gmx mit 2FA funktioniert? Meine Erfahrung bis jetzt ist, dass es Serverseitig von GMX (bei CalDAV/CardDAV) nicht unterstützt wird. In diesem Fall wäre deine Bewertung äußerst unfähr.

The functonality I was hoping for from 'Provider for Google Calendar' though could never get to work.

Hopefully in future it will be able to support copying Google event colours and push updates, then we will finally have truly functional calendar support in TB.
It's been a looong wait...

Einer der ganz wenigen Entwickler, die wirklich wissen worauf es ankommt. Seine AddOns sind essentiell und funktionieren perfekt. Und zudem auch noch hervorragender Support. Dankeschön!

Great. With the Provider for Exchange ActiveSync, this has synced the TB calender and address book with my outlook.com account, and now the Provider for CalDAV & CardDAV has added support for Google, it syncs the TB calendar and address book with my gmail.com account too. This means TB's calendar and address book sync with both the Calendar and People on my W10 laptop and the Calendar and Contacts on my Android phone, all with one consistent interface. Honestly, this out to be part of core Thunderbird, but as it isn't I'm really grateful to John for providing this for us. Superb add-on.

Hi John, thank you so much for this! This is what is really missing in T-Bird and you implemented it nice and easy. If I understand it correctly, you also sign responsible for QUICKTEXT. You provide my favorite tools, thank you very much from Mannheim.
