Outlook
OAuth push sync, missing events, and reconnecting.
How Outlook sync works
Push sync (OAuth) is the default for Outlook: Sync2Cal writes to a dedicated calendar it creates and never reads your other events. An ICS link is a slower alternative.
Events not showing in Outlook
If events are missing, try re-syncing at sync2cal.com/me. If that does not resolve it, disconnect and reconnect your Outlook account.
Outlook on iPhone or Android
Sync2Cal syncs to your Outlook account, not a specific device. Events appear on any device signed into that Microsoft account, including the Outlook mobile app.
