How to Get the Outlook Calendar in Apple Calendar?

First, we will find the ways to sync the calendar in the Apple Calendar, the steps to move the Outlook calendar files for instant access rather than syncing.

Method 1: Live Sync via Exchange

Here’s the process to export Outlook calendar to Apple Calendar on your Mac:

  1. Open Apple Calendar.
  2. Now, click Calendar > Add Account inside the menu bar.
  3. Select MS Exchange. 
  4. Go on to click Continue.
  5. Enter your Outlook account’s credentials.
  6. Verify that the Calendars checkbox is selected.
  7. Further, use Refresh Calendars inside the Accounts section for setting your preferred syncing frequency.

Once this setup is complete in its entirety, Outlook calendar events will be displayed within your Apple Calendar application. You can now confirm successful syncing by opening Calendar & then looking for specific Outlook events. If you had earlier used calendar delegation features in the Apple Calendar, you might need to disable them now for appropriate synchronisation functionalities.

For this, you have to go to Calendar > Preferences > Accounts > Delegation & uncheck all calendars.

Method 2: Manually Export/Import

  • In Outlook, go to File > Save Calendar and export the calendar as an *.ics file.
  • Open the Calendar.
  • Go to File > Import, select the *.ics file, and choose the calendar to add to the events.

Note: This method does not reflect the future changes, but it is best for instantly importing an Outlook calendar to Apple Calendar. You will need to repeat these steps each time you update.

Make use of distinctive colours for personal meetings, work appointments, travel entities, & family events. This type of visual differentiation will make scanning easy for you to schedule things better.
  • Try configuring notifications very thoughtfully to avoid too many alerts. Try to set different notification timings for various types of events.
  • Review periodically & clean up any old/unwanted calendar entries. Try removing all the outdated subscriptions so that sharing permissions remain appropriate. Keep such calendar names & descriptions, which are current & make sense.
  • While forming events, make use of consistent naming conventions & also include relevant details in descriptions. This makes sure that your events are clear & useful irrespective of the platform you are seeing them from.
