iCloud features that work differently in Outlook

Some iCloud features in Outlook work differently than they do on your Apple device. Here are a few tips to help you use Outlook with iCloud for Windows. 

Mail and Notes

  • VIP Senders folders aren't available in Outlook.
  • Any email rules you've created in Outlook won't be available in the email applications for your other devices or on iCloud.com.
  • Signatures are saved locally to your device. You won't see signatures you've created in Outlook on your other devices.

Notes isn't a separate application. Your notes are stored in an email folder. 

  • You'll find Notes you've created on your other devices in this folder.
  • Notes that you've posted to this folder from Outlook won't appear on your other devices, but you'll see them on any other computer using Outlook and iCloud for Windows signed in with the same Apple ID.
  • You can delete notes from this folder and they'll be deleted from your other devices.


  • Outlook will only import the first contact in a vCard set. 
  • If you need to add a vCard set to Outlook, import the set directly into iCloud.com or macOS Contacts. We will bundle the entire set for you and add them as individuals to your Contacts. 


  • When you add Calendar attachments to a Calendar entry in Outlook, you won't see them in Calendar for iOS or Calendar for macOS (or the other way around).
