This article explains how to connect your Outlook Calendar with your iPhone so that your appointments and events are always in sync, no matter where you access them from.

How to Sync Outlook Calendar with iPhone Through the Built-in Calendar App

This process relies on the iPhone’s ability to import calendars but does not synchronize Outlook Calendar with Apple Calendar. To sync an Outlook Calendar with Apple Calendar, a Calendar sync tool is required to directly connect the calendars.

To sync an Outlook Calendar with your iPhone, please follow the steps below:

  1. Open the “Settings” app on your iPhone: We’ll utilize the ability that the iPhone has to import other calendars like Outlook Calendar.

    Settings app iPhone
  2. Scroll down and tap “Mail.” This page is where your imported accounts in your iPhone are located. On this page, you can also add or remove your accounts.

    Settings app iphone - Mail
  3. Click “Accounts”: The Accounts screen allows you to manage all your connected accounts and add new ones.

  4. Tap “Add Account.” This allows you to add an account of the following: iCloud, Outlook, Yahoo, and other providers.

  5. Click “Outlook.com”: Apple will redirect you to the official Outlook login screen, where you have to enter your account credentials.

  6. Enter your Outlook email and password, and sign in.

  7. Enable Calendar Sync: After signing in, you'll see options to sync Mail, Contacts, Calendars, Reminders, and Notes. To sync Outlook Calendar with your iPhone, you have to select “Calendars” so your Outlook stays in sync with your iPhone.

    Settings app iphone - enable calendar
  8. Ensure the “Calendars” option is turned on to sync your Outlook calendar with your iPhone’s Calendar app.

  9. Check Calendar App: Open the iPhone’s Calendar app to see if your Outlook events are appearing. If not immediately visible, you may need to refresh the calendar or restart your iPhone.

What are the Common Challenges of Syncing Outlook with iPhone?

When syncing Outlook with an iPhone, users often face two primary challenges: sync delays, errors, and compatibility issues.

Sync delays and errors. You might not see updates quickly, or event details between your phone and other devices might not match, causing confusion. 

Compatibility issues. It can happen when the iOS version on the iPhone or the Outlook version on other devices is different. These mismatches can block the syncing process or cause errors, making it difficult to keep your calendar consistent across all your devices.
