How to Add Bcc Recipients in Outlook

Keep email addresses anonymous from other recipients

Use the Bcc field 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 fields in Microsoft Outlook. Using Bcc depends on certain circumstances, but is helpful when sending an email to undisclosed recipients in Outlook.

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