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

Tbsync is a very good software after Google. Thank you, but I have the following problems in using it:

1. Every time you start the calendar account in Thunderbird, you can't display the schedule. You have to delete the calendar before synchronization, and then synchronize it again. Please help. thank you!

iCloud-Einrichtung hat sofort funktioniert, man benötigt lediglich Username der Apple-ID und das Applikations-spezifische Kennwort aus iCloud. Perfekt!

Setting up iCloud works instantly. You only need the username of your apple id, and an application-specific password (as created in iCloud). Perfect!

Works perfectly on TB78 with Google Agenda & Contacts, very easy configuration ! thank you so much.
Install "Provider for CalDAV & CardDAV" and also "TbSync" from the same developer.
Then change this setting following the instructions from the developer : https://github.com/jobisoft/DAV-4-TbSync/issues/240

I use it for a while now. It is a bit verbose for my taste (which makes it look more complicated than it really is). It does a GREAT job in terms of functionality.

I use TbSync in conjunction with the Provider for Exchange ActiveSync. It allows me a complete and reliable synchronization with my Outlook calendar and contacts . It is in my view an essential extension of Thunderbird in any Windows environment, a must-to-have.
At the time of writing this review, I have it installed with Thunderbird 78.5.1 (64-Bit) and Windows 10 20H2 x64. It works flawlessly.

Took me 10 minutes to setup GMX, o365 and Google (unfortunately discontinued support). Only one Add-On to support all this providers - how good is that!?!
Keep up the great work and reconsider supporting google interfaces.
Thanks!

Thanks a lot John for your incredibly valuable work. I had been using Thunderbird for a long time, then left it because getting calendars and contact syncing was becoming a pain. After a few years, I came back to Thunderbird because of TbSync really.

I think TbSync is so good it should be embedded in Thunderbird. I read there are some plans to do that in the future, I'm really looking forward to it since I believe Thunderbird would benefit a lot from it.

Regarding the latest move to set Google support as experimental, I totally understand it and respect it. What people really don't understand is that this is a *free* add-on for a *free* software (which works great). It is so frustrating to read people demanding things yet not willing to pay a penny.

I hope despite being experimental Google support will keep working, as this is what attracts many users to use use this awesome add-on. Please keep up the good work :)

Thanks

I have tried and tried and tried to get this $%?&?? add-on to work and it DOES NOT. It is useless. The entire 78.5 version of Thunderbird is a disaster with many add-ons that had worked fine for years having been disabled. The final product is less than it was to the point where I'm seriously thinking of switching to an entirely different platform.;

40.000 users seem to use it just fine. Calling my addon $%?&?? is of course disqualifying you from any further (free) support.

Works like a charm to sync my own CalDAV/CardDAV server ie. calendars, tasks and address book on a Synology NAS.
