CalDAV does not update from Server
Hello,
I have two calendars in Thunderbird connected to my email server at the provider https://all-inkl.com/. The connection is done via CalDAV.
My problem is that the calendars do not synchronize with the changes on the server or do it in intervals that are not understandable to me. I have also connected the server via CalDAV to my calendar app on my phone and that works fine. Changes to events on my phone are synchronized to the server quickly and I can check the server to see them. However in Thunderbird, the changes do not arrive and even if I manually tell the calendars to synchronize, nothing happens. The only reliable way I have managed to make them update is closing Thunderbird and reopening it. Then the synchronization happens by itself within a minute.
Does anyone know how to address this problem?
Switching offline support on or off makes no difference, as far as I can tell by testing.
My system: Thunderbird 147.0.2 (64-bit) on Windows 11
Calendar settings:
- refresh calendar: every 5 minutes
- read only: off
- show reminders: on
- offline support: on
Thanks!
