How to Add Bcc Recipients in Outlook

Keep email addresses anonymous from other recipients

Use the Bcc (blind carbon copy) field in Microsoft Outlook to send an email message to one or more recipients without revealing email addresses to the other recipients. The Bcc field works like the To and Cc (carbon copy) fields in Outlook. Using Bcc depends on certain circumstances, but is helpful when sending an email to undisclosed recipients in Outlook.

The difference between Cc and Bcc is how recipients see who the email was sent to. When you use Cc, you're sending a copy of the email to all the recipients and they can see the email address of everyone included. Using Bcc, you can send a message, but all recipient emails are hidden for privacy reasons.

Instructions in this article apply to Outlook for Microsoft 365, Outlook 2019, Outlook 2016, Outlook 2013, and Outlook 2010.

Recipients added to the Bcc field are not visible to the other recipients of the message, even others who are also in the Bcc list.

  1. Open a new email message or reply to or forward a message.

  2. In a new message, go to the Options tab. In a reply or forwarded message, go to the Message tab.

    If the message you're composing is open in the Reading pane, BCC may already be displayed on the Ribbon. If it is, you can select it from there.

  4. In the Bcc field, enter the recipients whose addresses you want to hide from other recipients.

  5. In the To field, enter at least one email address. This can be your email address or another email address. The address in the To field is visible to every recipient, even the Bcc ones.

To enter an email address in the Bcc field quickly, select the To button to open the Select Names dialog box, highlight a name, select the Bcc button, then select OK when you've added all the recipients.
