Event missing, duplicated or late
Sync generally runs but individual events won’t play along? Here are the symptoms and their most common causes. (If nothing arrives at all, start with the checklist.)
An event is missing in the target
Section titled “An event is missing in the target”- Outside the sync window: further than 6 months ahead or older than 3 months → appears automatically once it moves into the window.
- All-day event: transferred as free by default → All-day events.
- Source not part of the sharing: is the event really in one of the selected source calendars?
- Polling delay: with Apple/KSuite/iCal sources, wait up to 5 minutes.
- Occurrence of a series: appears once it moves into the window → Recurring events.
Tip: the safety net fully reconciles every few hours — a lot resolves itself that way.
An event arrives late
Section titled “An event arrives late”- Google/Microsoft sources: typically under a minute. Apple/KSuite/iCal: up to 5 minutes plus possible provider caching (Outlook feeds are sluggish).
- Persistently slower? Contact us with a concrete example.
An event appears twice
Section titled “An event appears twice”- Two syncs, one target: do two syncs write the same source calendar into the same target? Each creates its own blocker — end one of them.
- Leftover blockers from an ended sync: cleanup runs in the background and can take minutes to hours → Ending.
- Reproducible true duplicates from one sync are a bug → support with an example, we’ll look right away.
A blocker stays although the source event is gone
Section titled “A blocker stays although the source event is gone”- Wait briefly: deletions arrive with the next sync round, or at the latest with the safety-net reconciliation.
- Deleted/moved the blocker by hand? The other way round applies: blockers created by Kalender Sync are restored on the next reconciliation — they belong to the source. To get rid of an event → delete it in the source.
- If a ghost blocker persists: support with title + time.
