I have a E-Mail account. (free E-Mail regsitration, german ). I can not sync my phones addressbook via carddav and my phones calender via caldav.

The calddav address is: and the carddav address is: Calddav, Carddav

Similar issues should exist with, and (registration (free), english) which belongs to the same company (United Internet).

Gmx caldav Gmxcarddav

On synchronization of the phone book with carddav works well, synchronization of the calender with caldav does not work.

What do I have to enter as username and as optional caldav address and optional carddav address?

Tested with sailfish x.

It didn't work for me as well, but since I changed to everything is working.

Probably not what you expect as an answer, but why not take this as a trigger to fully move away from United Internet? With you already made a very good choice.

Not an answer, but my posteo debugging experience, in case it helps:

  1. I first let Sailfish (X) search for Caldav and CardDav itself by only providing the main server (including https:// and the port number). I used my regular mail login credentials, but of course this differs per provider.
  2. The CalDav was found automatically, so the optional path for CalDav could be left empty
  3. CardDav was not found, so the optional path needed to be used. IIRC I provided the full path including the server that is already mentioned in the Server URL field. I am not sure a relative path is sufficient or not.
  4. You may have to check the CalDav and CardDav checkboxes in the account after creating the account. In my case this was needed because CardDav was unchecked after the first try.

Are you able to collect sync logs (see for information on how to collect those) and send them to chris dot adams at jolla dot com so that we can investigate the issue further? I have seen another report about which may be related (see for that one) but currently don't have enough information to determine precisely what the issue might be or how to fix it.

There is this old post back from 2015 where it is explained what URL to use for for caldav:

Maybe you can try the steps described there and report feedback here or there?

The reason i ask are my own problems with gmx and caldav xD I followed the steps and although i get my calendar and can "upload" evetns from phone to server i cannot recieve any events from server to phone.

System: Jolla1 on

Hi, have you ever been able to fix this? I'm asking since I have still the same issue. I can add events from phone to server, but cannot recieve events from server to phone (nor can I remove events from phone to server). System: Sailfish X on Xperia XA2 Plus
