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.

Brilliant extension!

I only wish the synced calendars could show up in the agenda tab as "calendar (account)" instead of "(account) calendar" but that's detail.

Love it. We'll evaluate it deeper and most certainly promote its usage in our University.

This add-on is fantastic and should really be part of the default Thunderbird program. It is very straight forward to use and required very little input to setup with my mailbox.org account.

All of my calendars, contacts and tasks are synced with my provider. Not that it affects me, but there are also other addons for different providers that work with TbSync.

I have two outlook.com accounts. While Thunderbird's IMAP support syncs emails, TbSync (plus the related Provider for Exchange ActiveSync) syncs calendar, tasks, and contacts. So far TbSync has been perfect - very fast and stable.

Works 100% with mailbox.org, the cheapeast, most secure all-in-one replacement for outlook. Synchronization was automatically configured for multiple contact groups, multiple calendars, and even my tasks list. I could not be more impressed with this add-on's support for mailbox.org.

This works flawlessly between Thunderbird and my university's Office 365 account. I especially appreciated the warning about the upgrade to Thunderbird 68. That's John looking out for us. (I made a contribution. Did you?)

Fantastic. Effortlessly setup iCloud Calendar and tasks which give me full integration with my iPhone. Awesome. Included this in this guide to getting off of Gmail: https://lioncx.com/2019/07/26/gmail-alternative/

I use the latest version of Thunderbird and my business email is from a zimbra server. This app made the caldav/carddav connection perfectly simple. It easily connected to the server and it automatically found all of the calendars, and then all of the contact folders.

Un must pour intégrer des comptes d'agendas et contacts à son Thunderbird. Il faut parfois utiliser les "provider" adéquats en fonction du format (caldav, exchange, etc...)

I have installed TbSync withDAV-4-TbSync and was unable to create a CalDAV/CardDAV account: it got lost in an infinite loop downloading folders.

Same problem as TeeBee (April 25, 2019) - the contacts got synchronized upon initial account add. But never since. There is also no option to manually sync the addressbooks.
Calendar is working on the other hand.
Using nextcloud as backend.

Same answer: Contact me directly. Either by sending in a bug report under help in the tbsync manager or by using my public email address listed here:
https://addons.thunderbird.net/de/thunderbird/addon/tbsync/

I can only guess, that you did not enable auto sync...
