Distinguish Between BCC or CC Recipients in Outlook.com

When you send an email in Outlook.com, copy it to other recipients using the carbon copy function. To copy other recipients without revealing names and addresses to others who receive the message—such as when you email a group whose members do not know each other—use blind carbon copy instead. Also, use Bcc to prevent recipients from using a reply-all tool to send their responses to the entire group when only you should receive these responses.

Add Bcc or Cc Recipients in Outlook.com Messages

To add Cc or Bcc recipients to an email you are composing on Outlook.com:

1. Select New message.

2. In the new message, select Bcc to add the Bcc field to the message header. Or, select Cc to add the Cc field.

3. Enter recipients' email addresses in the appropriate carbon copy fields.

4. The email will be copied or blind copied to those you indicated.
