As far as I can tell by looking at the audit logs it seems to me that FolderCompletion events for remote devices are only triggered when the host is fully synced by itself.
This is of course the intended case, but I just want to check if it is reliable or if I should check it myself.
Ok. There was still no confirmation or denial that FolderCompletion events only happen when the host on which the events are received is fully in sync.
