  3. Enter your iCloud email address (for example, name@icloud.com), then select Continue.
  4. Sign in with your Apple account and complete two-factor authentication when prompted.
  5. Review and accept the permissions requested, then select Done.

Your iCloud mail, calendar, and contacts begin syncing. Your iCloud calendar appears in the Calendar view, and your contacts appear in the People view.

  2. After installation, launch the iCloud app and sign in with your Apple account and password.

Troubleshooting

The sync Contacts and Calendars option is missing

  • If the iCloud for Windows app doesn't show the Contacts and Calendars option, it might skip the option because the app didn't detect a supported installation of classic Outlook for Windows on the PC. To sync your iCloud calendar and contacts on these devices, use new Outlook for Windows and add your iCloud account directly.
  • iCloud for Windows doesn't have a native ARM64 version. On ARM-based Windows devices, it runs by using x86 emulation. As a result, you might experience slower performance or find that some features don't work as expected.
