If you can't sync your Outlook contacts and calendars from your PC to your iOS device using iTunes for Windows, you might want to set up iCloud for Windows. Using iCloud for Windows, you can keep your contacts, calendarnotes, and documents up-to-date across all of your devices.

If you prefer to sync manually using iTunes, try the steps in this article.

Before you begin

System requirements

Syncing notes via USB isn’t supported in iTunes 12.2.2 and later or iOS 9 and later. Learn how to use iCloud to sync your notes with Outlook.

If you can't sync

If you can't sync using iTunes, or your contacts and calendars don't sync as expected, follow the steps in each section.

Reset your iTunes sync history

  1. Open iTunes.
  2. From the menu bar at the top of the iTunes window, choose Edit > Preferences.
  3. Select the Devices tab.
  4. Click the Reset Sync History button.
  5. Try to sync again.

Run iTunes Diagnostics

Use iTunes Diagnostics to run the "iPhone/iPod touch sync test" while your device is connected to iTunes. If the test passes, try to sync again. If your contacts or calendars still don’t sync as expected, there could be an issue with your Windows user account, your Outlook profile, or the data itself.

Isolate the issue with a new Windows user account

You can log in with a new user account to figure out if the unexpected behavior is related to a specific user or a system-wide issue.

  1. Create a new user account in Windows 10Windows 8, or Windows 7.
    This isolation will ensure the steps you're applying are appropriate for the type of issue occurring. If you prefer not to create a new user account on your Windows system, continue to the User Account Issues section.
  2. After you create a new user account, sign in to that new user account and open Outlook. After Outlook opens, create a local data file (PST) and add a few contacts and calendars to Outlook.
    Some versions of Outlook may require you to have your original install disk.
  3. Connect your iOS device and try to sync again.

If all of your content syncs correctly, the issue is likely related to the specific user account you're trying to sync. Continue to the User Account Issues section. 

If your content didn’t sync as expected, use iTunes Diagnostics to run the "iPhone/iPod touch sync" test while your device is connected to iTunes. If the test passes, try to sync again. If your data still doesn't sync with the new user, follow the steps in the system-wide issues section.
