How to Fix iPhone Calendar Not Syncing With Outlook

The Outlook Calendar is a great tool that allows you to create appointments and events, organize meetings, keep track of your schedules, and more.

One of the best things about the Calendar app is that you can sync your iOS calendar with an Outlook calendar, meaning that you can view all of your appointments in one single app. The coolest part is that the Outlook Calendar is fully integrated with emails, contacts, and phones. When you have an appointment email, it will automatically sync to the Calendar in Outlook, so that you can keep track of it quickly.

However, there are times when an iPhone calendar is not syncing with an Outlook Calendar. This is a common problem that touches many iPhone, iPad, and iPod Touch users. Luckily, there are several fixes for this annoying bug. 

In this tutorial, we will show you how to fix an iPhone calendar that is not syncing with an Outlook calendar. Before we move any further, we suggest you try restarting your iPhone to see if this problem is fixed. If it persists, make sure you read on.

Why is Your iPhone Calendar not syncing with Outlook?

There are several reasons why an iPhone calendar fails to sync with Outlook. Mainly, the problem is with data not syncing to the server properly. Another cause is you select the incorrect calendar when creating an event on your iPhone. In this case, check your iPhone’s default calendar. 

If this is the first time you are syncing your iPhone calendar with Outlook, then make sure you set it up correctly. Your Outlook account needs to be linked to your iPhone for the syncing to work. 

How to fix iPhone calendar not syncing with Outlook

We will walk you through all the possible fixes for the problem in the section below. 

Make sure you use Wi-Fi

All your data will be sent to the online servers when the syncing is complete, which allows you to access your essential notes or events across all devices. 

However, if data syncing fails, then there is a good chance that your iPhone is now on a cellular connection. In this case, try switching to a Wi-Fi network to see if the problem is dealt with. To do this, open Settings > Wi-Fi and your device will search for available networks. 

Turn off Airplane Mode

Enabling Airplane Mode will shut down all of your wireless connections. As a result, your iPhone won’t connect to any online servers, so data syncing will fail. 

Make sure you have Airplane Mode turned off while syncing your data with Outlook. Swipe down from the top right corner, then tap the airplane icon in the top left corner of Control Center to turn it off. 

Disable Low Power Mode

Low Power Mode is an excellent addition to iOS. Once enabled, it will turn off all of your background activity, including downloads, data syncing, location services, and more, to save more battery. 

If your iPhone is now on low battery, charging it will automatically turn off Low Power Mode. Of course, you can manually disable it by heading to Settings > Battery and turning off the switch next to Low Power Mode. 

Close apps on iPhone

There are times when some iPhone apps get glitchy and prevent data from syncing properly with Outlook. So, it’s a good idea to close all apps entirely before you start syncing data between services.

Perform a long swipe from the bottom of the iPhone’s screen to trigger the App Switcher. From here, swipe up on each app to close them. 

Make sure you are up to date

If none of the above solutions works, then there is a good chance that you are now on an outdated Outlook app. A new update usually includes bug fixes and performance improvements, so it’s a good idea to stay up-to-date.

Simply, open the App Store on your iPhone, hit Updates, and check if you have any available updates for the Outlook app. 

Ensure your Outlook Account is connected to your iPhone

For data syncing to work correctly, you need to be logged into the correct Outlook account on your iPhone. Open the Settings app on your iPhone, and select Passwords and Accounts. From here, you should see all of your accounts that are currently linked to your iPhone. If Outlook is not listed, then tap Add Account to add it.

Once you’re done adding your Outlook account to your iPhone, check if you have granted Outlook full access on your iOS device. To do this, head over to Settings > Passwords & Accounts > Outlook. From here, turn on the switch next to Calendars.

Make sure your preferred Outlook is selected on iPhone

You can add several Outlook calendars to your iPhone. So, make sure your preferred one is selected. To do this, open the Settings app, then choose Calendar > Default Calendar. While creating a new event in Calendar, hit Calendar and select your preferred Outlook to save it. 

Sync via iTunes

If nothing works, try syncing your data via iTunes. To do this, connect your iPhone to a computer using a cable, then launch iTunes and select Devices. From here, select iPhone > Info > Calendars > Sync Calendars From > Outlook > All Calendars > Apply.
