TRLD: New CalDav ( calendar created, all entries in default personal deleted

Existing device accounts before adding Posteo account:

  • Default personal calendar
  • Default Birthday calendar
  • Google Calendar (2-way)
  • Facebook Calendar

I added a Posteo calendar via "Add account -> CalDAV and CardDAV" to my existing device accounts (followed this how-to).

After a sync to the new device calendar, called "posteo", all my existing entries from "Default personal calendar" were deleted.

How do I get my calendar entries back? And why did this happend? I did not touch my personal calendar at all.

All entries are left intact in /home/nemo/.local/share/system/privileged/Calendar/mkcal/db. But every entry has a filled DateDeleted (unix time there equals creation date of the new posteo calendar).

  • The link you mention is about connecting an already existing posteo calendar to your jolla - not about adding another calendar to posteo.
  • It does not overwrite any other, foreign calendar, and can only sync using the personal credentials and path you specified when creating the caldav account.
  • Therefore, if you have more then one calendar at posteo, you should be able to add one caldav account for each of them, f.e.,,, ..., but I for myself never tried that. But you can test the URL with your original path and credentials in any browser. With a wrong path you will recive an error message as there is no calendar available.
  • Which host's calender is empty now? Google's overwrote posteo's, or posteo's default was overwritten by posteo's birthday, or facebook overtook google... ?
  • Best advice: next time export your calendars to ICS file before changing things. The moment after ist is to late...

It was really confusing, sorry. I tried to make it more understandable.
