This was a lifesaver app as I slowly try to migrate out of Google's clutches. The steps on how to generate the permissions on the Google API site were really good. I learned a lot! Thanks for your hard work. Und noch mal vielen Dank!

Its good. But however when I update a repeated event to the calendar into my Outlook's calendar, its deleted automatically after sync. Bug?

But for 1 event that's working fine. I can see the update write in the Outlook's calendar.

Thanks for the great addon. It allowed me to sync Outlook calendar.

It is a great add-on that I use to sync my contacts with Outlook, so that I can keep them updated on all my devices (using the add on: Provider for Exchange ActiveSync). Thank you you for keeping it up to date with the newest Thunderbird releases.

This works brilliantly most of the time. BUT every so often it will randomly ( though I think it might possibly be when there's been an update rather than truly random) refuse to accept the account credentials. No only refusing to accept the current stored credentials, but refusing to accept the password when manually retyped in (endless attempts). The account has to be deleted and set-up again.
I'd hazard a guess that it's corrupting the stored password in some manner, but refusing to replace it.

Ich habe die beiden Add-ons "TbSync" und "Provider für CalDAV & CardDAV" von John Bieling installiert. Nun kann ich mein Adressbuch und meinen Kalender problemlos zwischen dem E-Mail Center der Telekom und Thunderbird synchronisieren. Eine ausführliche Anleitung zu den Einstellungen gibt es bei "Telekom hilft":

Je l'utilise pour les calendriers sous Outlook en ligne, simple et efficace.
Using it for Outlook online, very efficient. Good job.

Great and obligatory add-on. I am using it with Google Calendar and with Office-365 (calendar and address book).
The only request would be: when creating an event in Office 365, the field "Show time as" can only be "busy" or "free". Meanwhile, in Outlook, the field "Display as" can be "Free", "Working elsewhere", "Tentative", "Busy", "Out of Office". When my colleagues create a meeting with Outlook, it complains only if I am "Out of Office", which I cannot do in Thunderbird + TbSync, so they invite me to meetings during my days off, entered in Thunderbird/TbSync with "Show time as: busy".

Works well with our Windows 10 PCs.

But does not work on MacBook Pro, MacOS 10.15.7, Thunderbird 78.10.1 (64 bits) .
We cannot add accounts (Provider for CalDAV & CardDAV). It simply does nothing when selecting the option.
Tried to unsinstall all modules and re-install. With no success.

This addon is very cool, but has currently a serious issue with Teams/Office 365 event reschedule: when a reschedule is accepted in Thunderbird and the sync is performed the change is not performed (the event stays at the same time as before).
If this was working the add-on would be perfect...

Either does not work or has stopped working with Microsoft Teams calendar events.

I am using Thunderbird 78.7, TbSync 2.20 and Provider 1.20

Suppose, I create a new meeting directly using Microsoft Teams, then the event is not synced. However, the event gets synced to Outlook 365.

Worked really well for Google accounts. Thanks for the article on enabling experimental support for the extension.

Hello
we are using the latest version of thunderbird tbsync and caldav
we have loaded 10 calendars
so far everything works fine
only one little thing is annoying
if i have loaded the calendar from the person max1 i can also give it a color in thunderbird although it is write-protected with me which is ok
but when tbsync is called and synchronized, the color changes back to the original one that the owner of max1 specified
can you change that or is it due to thunderbird or tbsync

Easy to use, functional, versatile, extendible - excellent addon! Also had to equip Outlook with DAV functionality via plugin, but that was much more of a hassle. I'm using the addon together with its Provider for CalDAV companion. THANK YOU to the author for providing this!

[HU] Nagyszerűen működik, a CalDAV- és CardDAV-integrációs moduljával szépen kezeli a nextcloudos és mailbox.org-os fiókom naptárát és névjegyeit.

[EN] Works great, with the CalDAV & CardDAV Provider both my Nextcloud and Mailbox.org account is properly synced.

Together with "Provider for CaldDAV & CardDAV", "Provider for Exchange ActiveSync" and "lightning", It finally allows me to access both outlook and google calendar and address books . It perfectly works on the latest thunderbird version 68.10.0
