How to set up a shared family calendar on iPhone using Microsoft Outlook

Haven for Families · Guide

If your family uses Microsoft accounts — Outlook, Hotmail, or a Microsoft 365 subscription — you can share a calendar across iPhones. The process involves Outlook on the web, the Outlook iOS app, and a fair amount of patience. Here's how to do it.

What you'll need

A Microsoft account for each person (Outlook.com, Hotmail, Live, or Microsoft 365)
The Microsoft Outlook app installed on each iPhone (free on the App Store)
Access to outlook.com or a browser — some steps can't be done from the iPhone app

⚠️ Heads up: Microsoft's calendar sharing has different behavior depending on whether you're using a personal Microsoft account (Outlook.com) or a work/school Microsoft 365 account. This guide covers personal accounts. Work accounts may have admin restrictions that prevent sharing outside your organization.

Part 1: Share your calendar from Outlook on the web

Calendar sharing permissions in Microsoft's system have to be set up from a browser, not the iPhone app.

Step 1

Go to outlook.com in a browser and sign in with your Microsoft account.

Step 2

Click the Calendar icon in the left sidebar to switch to calendar view.

Step 3

In the left panel, find your calendar (usually labeled with your name or "Calendar"). Right-click it and select Sharing and permissions.

Step 4

Enter the Microsoft account email address of the family member you want to share with. Choose their permission level — Can edit lets them add and change events; Can view all details is read-only.

Step 5

Click Share. They'll receive an email invitation.

Step 6

Repeat for each family member. Each person needs their own invitation.

Part 2: Accept and view the shared calendar on iPhone

Step 7

The invited person opens the email invitation on their iPhone and taps Accept. This opens in their browser and logs them into their Microsoft account.

Step 8

Open the Outlook app on their iPhone. Tap the calendar icon at the bottom. Tap the three-line menu in the top left and look for the shared calendar under the account name — it should appear there after acceptance.

Step 9

If the shared calendar doesn't appear in the app, go to outlook.com in a browser on their phone, navigate to Calendar, and check whether the shared calendar is visible there. If it is, the app may need to be signed out and back in to refresh.

Part 3: Adding events to the shared calendar

Step 10

When creating a new event in the Outlook iPhone app, tap the Calendar field in the event editor. Switch from your personal calendar to the shared family calendar. This step is easy to miss — events added to the wrong calendar won't be visible to the rest of the family.

Step 11

There's no way to set the shared calendar as your default in the Outlook app. Every family member has to manually select it every time they create an event.

⚠️ iPhone Calendar app users: If you want Microsoft calendar events to appear in Apple's built-in Calendar app (not just the Outlook app), you need to go to Settings → Calendar → Accounts → Add Account → Outlook and sign in separately. Even then, shared calendars from other people may not sync correctly to the native Calendar app — this is a known limitation of Microsoft's calendar protocol on iOS.

What Microsoft Outlook doesn't do for families

Microsoft Outlook is a powerful tool for work. As a family calendar on iPhone, it has significant gaps:

Designed for work, not families. The interface is built around meetings, invites, and business workflows — not kids' activities and family pickups.
No morning briefing. There's no daily summary for your household. Each person manages their own view.
No event assignment. No way to tag which parent is doing a pickup — you'd write it in the event title or body.
No photo import. Schedule screenshots from coaches or schools have to be retyped manually.
Poor native iPhone integration. Microsoft calendars don't behave the same as iCloud calendars on iOS. Siri, Focus modes, and lock screen widgets work best with Apple's own calendar system.
Shared calendar sync can be unreliable. Shared Outlook calendars on iOS have a long history of sync inconsistencies, especially on personal (non-365) accounts.
Everyone needs a Microsoft account. For iPhone families who live in the Apple ecosystem, this is an unnecessary friction point.
