Outlook calendar not syncing with iPhone

I’ve compiled a list of quick fixes that will hopefully help you with the Outlook calendar not syncing with iPhone issue.

1. Check if Outlook calendar is displayed among other calendars

Open the Apple Calendar app, click on Calendars at the bottom, and check if your Outlook calendars are ticked to be displayed.

2. Make sure that the Airplane mode and Low Power mode are not enabled

Background sync won’t work if these are on. Turn these modes off and see how it goes.

3. Check if the calendar sync is enabled in calendar settings

Go to Settings > Calendar > Accounts > Outlook and make sure that the Calendars toggle is on.

4. Change new data Settings for Outlook

By default, newly added accounts are set to fetch new data, i.e. check for and download new data in pre-set time intervals rather than get new data as soon as it’s available on Outlook servers (the so-called Push option). It is possible to switch from one to another. Go to Settings > Calendar > Accounts > Fetch New Data > Outlook > switch to Push.

5. Allow calendars to use cellular data

If you mostly use mobile data, check if calendars have access to it. Go to Settings > Mobile data > toggle Calendar on. Alternatively, switch to Wi-Fi connection since data syncing can be delayed when your iPhone is on a cellular connection.

6. Remove and re-add the account

Go to Settings > Calendar > Accounts > delete your Outlook account. Restart your iPhone and navigate once again to Settings > Calendar. Then click Add account. Choose Outlook from the list and enter your account credentials. Choose what types of data you want to transfer from your Outlook account to your iPhone and click Save. That should do the trick.

✔️ If none of them worked out, please refer to the first part of this tutorial.
