Hi, I am considering moving from Thunderbird/Lightning to KMail/Korganizer but got stuck with syncing my CalDav based calendars.
I can add the calendars without a problem but none of the existing online events get synced.
What makes this even more strange is that when I create an event locally it will be synced to the online calendar, if I update the event name it will be visible online right away.
However, when I send myself a meeting request and select add to calendar in KMail it will show online but not locally?

After searching the web for this problem I had a look at .xsessions and I can see the following section over and over again:

Code: Select all

org.kde.pim.maildirresource: Got incomplete ancestor chain: Collection ID: 24    remote ID: ""
   name: ""
   url: QUrl("akonadi:?collection=24")
   parent: 22 "2017 my@emailaddress.com"
   resource: ""
   rights: QFlags(0x1|0x2|0x4|0x8|0x10|0x20)
   contents mime type: ()
   isVirtual: false

   timeout: -1
   sync on demand: false
   local parts: ()
    CollectionStatistics:
      count: -1
      unread count: -1
      size: -1


To me this looks unrelated, a problem with one of my email archive files, but I thought I'd post it anyway.

Has anyone got an idea where and what to check? Any log files?

I am running Kubuntu with all the latest updates.

Thanks
Thomas
