Sign out and back in to iCloud Control Panel

Signing out of iCloud Control Panel and signing back in will reconfigure Outlook for use with your iCloud account. 

Important: Any attachments you added to calendar events from Outlook will be lost. All of your other data is stored in iCloud, and will be downloaded to your PC when you sign back in with iCloud Control Panel.

    In Windows 8: Go to the Start screen, then click the iCloud tile.

  2. Click Sign out.
  3. When prompted to save or delete your data, click Delete. If prompted to view your iCloud Photos folder, click Cancel.
