ℹ️ Support

Operating system and version : Windows 10.

The issue you are facing: I don’t know which contact is causing the problem.

Is this the first time you’ve seen this error? (N): N

Steps to replicate it:

  1. I’ve changed a contact, and also moved three contacts from one folder to another in Outlook.
  2. CalDav ran automatically
  3. I got an error (as title)

The start of my CalDav sync report:

I’d start with these 4 contacts, there is a high chance that it is one of them.

Not sure if that corresponds to the UID of the contact in the database (oc_cards/oc_cards_properties).

Belatedly… What happens is that it fails once or twice and then works without any errors being reported. Yes, I did check the four new contacts but there’s nothing unusual about them
I can’t see anywhere in the Outlook UI that enable me to find the UID of a contact (if that’s what the log is showing) and although I was a Windows/Outlook Developer in a previous life, I’ve been retired for several years now and I can no longer remember how you access fields directly from the database :slight_smile:
Thanks for replying anyway
