Syncing problem with SHARED Microsoft 365 calendar in native iOS App

When using the native iOS calendar app, new items you add to a M365 calendar that has been shared to you do not sync. If you add an item as an all-day event, it will sync properly. You can edit and delete items that others created… those sync properly. The calendar owner using the same iOS native app does not experience this ’Adds won’t sync‘ issue.


This is clearly a bug in the iOS calendar app. Very frustrating!


The Outlook app on the same iOS device does not have an issue. But the Outlook calendar is nowhere near as good to use as the iOS calendar, which is why I’m trying to do this.


Anyone who can solve this one will be my hero!

Hi SammySRID,


Regarding using an Outlook account with your iOS Calendar, check to see if it's the default account using the steps below found in the article here: Set up multiple calendars on iPad - Apple Support


"Set a default calendar

You can set one of your calendars as the default calendar. When you add an event using Siri or other apps, it’s added to your default calendar.

  1. Go to Settings  > Calendar > Default Calendar.
  2. Select the calendar you want to use as your default calendar."
