Enabling BCC in Outlook for Mac
BCC (Blind Carbon Copy) is a method with which a message can be sent to additional recipient(s) without the main recipient being aware of who’s been included.
By default, Outlook only has the To:, CC: and Subject: fields when creating a new e-mail

To enable the BCC: field, click the “Options” tab at the top and click the button labeled BCC.
