How to Add BCC in Outlook (Step-by-Step Guide)

When sending emails, sometimes you want to copy someone discreetly without other recipients knowing. That’s where BCC (Blind Carbon Copy) comes in. Microsoft Outlook makes it easy to add BCC recipients—whether you’re using the desktop app, Outlook on the web, or the mobile app. This guide will show you exactly how to do it.

What Is BCC in Outlook?

BCC stands for Blind Carbon Copy. It allows you to send an email to multiple recipients, but the BCC addresses remain hidden from everyone else.
This is useful when:

• You want to maintain recipients’ privacy.
• You’re sending newsletters or announcements to a large group.
• You don’t want others to know who else received the email.

• Use BCC for large groups: Protect people’s privacy by not exposing everyone’s email addresses.
• Avoid reply-all chaos: Recipients can’t reply to everyone when they’re in BCC.
• Be cautious: Don’t use BCC to hide communication in professional settings—it can appear sneaky if discovered.
