How Outlook sync works

Sync2Cal offers two ways to add a calendar to Outlook: connect your Microsoft account for push sync, or subscribe using an ICS link. We recommend the account connection for direct updates.

Connect your account

Open a calendar on Sync2Cal, choose Sync to Calendar, select Outlook Calendar, and follow the account-connection prompts. Sign in on Microsoft's authorization screen using the account where you want the events.

Sync2Cal creates a dedicated calendar and sends event updates to it. Check that calendar is selected for display in your app. Delivery can be delayed by processing or connection errors; check the sync status if events do not appear.

What permissions does Sync2Cal use?

Microsoft grants Calendars.ReadWrite, which is broader than access to a single calendar. Sync2Cal uses the connection to manage the calendars it creates for you. Microsoft does not offer the same app-created-only permission used for our Google connection.

You enter your provider password on its sign-in screen, not into Sync2Cal. See calendar permissions and privacy for the difference between Google and Microsoft access.

Add a subscription link instead

If you prefer not to authorize an account connection, use the calendar-link option. Add the link in Outlook on the web, under Add calendar > Subscribe from web.

Your calendar service decides when to fetch changes from a subscribed feed. This can take hours; it is not the same delivery method as push sync. How updates work.

A file uploaded through an import option is different: it creates a snapshot without ongoing updates. Importing versus subscribing.

If something is missing

Check the account and calendar visibility first, then use missing-events troubleshooting. If it works on the web but not your phone, use the device checklist.

Disconnecting the integration affects its managed calendars; do not use it as your first refresh step. If you want to stop a calendar, follow the removal guide.

After connecting, see event settings and reminders. For a source change, see postponed and rescheduled events.
