2. Use Wi-Fi to Sync Calendar With Your iPhone

One of the reasons why Outlook calendar might not be syncing with iPhone is because there’s no good connection between the servers and your phone. The Outlook and iPhone calendars can sync properly when the data is sent to online servers and downloaded to a device.

This process is delayed when using a cellular connection. Some iPhones don’t allow these actions when using cellular data. You must turn off your cellular data and connect to Wi-Fi. Wait several minutes and check the calendars have synced.

3. Check if Calendar Syncing Is On

Your Calendar app moves all of the schedules and other data to iCloud. If there are issues with iCloud or you don’t have enough storage, your iPhone calendars won’t sync. You must ensure the app can read and write data from iCloud.

Here’s how to activate Calendar on iCloud:

  • Step 1:Tap settings.

4. Enable/Disable Airplane Mode

Internet connectivity issues are among the most common problems preventing Outlook Calendars from syncing with iPhones. When your Airplane Mode is turned on, it prevents data from syncing since the devices can’t connect to online servers.

Sometimes it can work with Airplane Mode on, but sometimes this feature disables syncing. There are no rules. That’s why you should try toggling Airplane Mode. If the Airplane Mode is on, turn it off and connect to a Wi-Fi network. Wait several minutes to see if the calendar is syncing.

Here’s how you can do this:

  • Step 1: Go to Settingsand tap on Date & Time.
