One-Way Sync

How one-way calendar sync works in Calendox.

A one-way sync copies events from a source calendar to a target calendar. Changes in the source are reflected in the target, but changes made directly in the target are not propagated back.

Use cases

  • Mirror your work Outlook calendar into your personal Google Calendar so you can see work events without switching apps.
  • Share a team calendar's events into individual member calendars (read-only view).
  • Maintain a backup copy of one calendar in another provider.

How it works

  1. On sync creation, Calendox performs an initial copy of all existing events from source to target.
  2. Calendox registers a webhook with the source calendar's provider.
  3. When an event is created, updated, or deleted in the source, the provider notifies Calendox within seconds, and Calendox applies the change to the target.

Changes made directly in the target calendar are not touched by Calendox — they remain as-is until the source event is modified.

Limitations

  • One-way sync requires the source calendar to support webhook notifications (Google Calendar and Microsoft Outlook both do).
  • Deleted events in the target that were originally synced from the source are not re-created unless the source event is modified.
