--- Comment #1 from Christian Quast <wildc...@tzi.org> --- By accident I figured why some contacts are proposed for completions while others are not: I first observed this behaviour after a clean install of KDE 5.x (openSUSE 42.x). I did't not keep / copy any settings from my old KDE installation. I then set-up Kontact to connect to my owncloud/nextcloud and mail servers. My contacts were synced to my local computer and I could see them Kontact / KAddressbook. I now realised that only those contacts are suggested for completion in KMail that I have modified locally in Kontact / KAddressbook, others are not. The steps to reproduce this should be as follows: No suggestion: * remove all akonadi / Kontact related settings, caches, * configure kontact to sync contacts from an owncloud/nextcloud server (maybe others?), * set-up an E-Mail account, * wait for remote contacts to be synced, * write a new E-Mail to a contact in the address book, * and wait for suggestions -> no suggestions should be found. Working suggestion: * in addition to the above, modify any of the contacts locally, e.g. add a random E-Mail address, * click 'OK' to save changes, * write a new E-Mail to a contact in the address book, * and wait for suggestions -> a suggestion should be found.
