After Synchroniszing with CalDav from Outlook in some Groups cannot be displayed cause there is the error message “Contact not found” (Kontakt nicht gefunden). Unfortunatly there is no more information. In the Log files I could not find any entry so I am stuck what to do.
I praised Nextcloud as a real alternative to google (snychronizing with DavDroid) and offered it for a few friends but now I am in a pretty pickle.
Deleting and adding new contacts unfortunatly do not do the trick and I cannot reset all to nothing cause in Outlook there could be troubles.
Has anybody some suggestions or had similar issues?
