How to Enable Bcc in Outlook for Windows 11
The Outlook for Windows app offers a modern interface for managing your Microsoft 365, Outlook.com, and Gmail accounts. A vital tool for email privacy is the Bcc (Blind Carbon Copy) feature.
Why use it? It allows you to send messages to multiple people without revealing their email addresses to others. What happens when done? Your recipients only see the names in the ‘To’ field, protecting your contact list from being shared.
New Outlook vs. Classic Outlook
It is important to distinguish between the New Outlook and Classic Outlook. The New Outlook is a web-based experience, while Classic Outlook is the traditional desktop software. The interface for enabling Bcc differs significantly between these versions. In Classic Outlook, you typically find the Bcc option under the ‘Options’ tab in the ribbon. In the New Outlook, it is integrated directly into the message composition window.
How to show the Bcc field in New Outlook
Open the Outlook app from your Start menu. Click the New mail button.

In the message window, look to the right of the To field. Click the Bcc button.

This makes the field appear for your current message.

How to always show the Bcc field
To make Bcc persistent, click the Settings (gear icon) at the top right.

Click Mail, then Compose and reply.

Select your account and check Always show Bcc.

Save your changes. Note: This setting is per-account.
Bcc Best Practices and Privacy Risks
Using Bcc is a standard practice for maintaining recipient visibility and privacy. However, be careful. If a recipient in the Bcc field hits ‘Reply All’, their identity is revealed to everyone. Always use Bcc when sending newsletters or group emails where recipients do not know each other. Learn more about how to use Outlook effectively to manage your communications.
Troubleshooting Missing Bcc Options
If you cannot find the Bcc field, ensure your app is updated. Sometimes, a corrupted installation requires a repair. Note: If you are on a managed corporate machine, you may need admin privileges to modify certain registry keys, such as those located in HKEY_CURRENT_USER\Software\Microsoft\Office\16.0\Outlook\Preferences. Always consult your IT department before changing system settings.
Summary
The Bcc feature is essential for email privacy. Whether you are using the New Outlook or Classic Outlook, you can easily enable it to hide recipient lists. By following the steps above, you can toggle it per-message or set it as a default. Always remember that Bcc is a tool for privacy, but users should still be cautious when using ‘Reply All’ to avoid accidental data exposure.
Can I set Bcc to be on by default for all emails?
Yes, you can enable this in the settings. Navigate to Settings, select Mail, then Compose and reply. Check the box labeled ‘Always show Bcc’ for your specific email account. Once saved, the Bcc field will appear automatically every time you compose a new message or reply to an existing one.
Does the recipient know if they are Bcc’d?
No, recipients in the Bcc field cannot see other Bcc recipients. They only see the sender and anyone listed in the ‘To’ or ‘Cc’ fields. This is why it is an essential tool for maintaining privacy when emailing large groups of people who should remain anonymous to one another.
Why is the Bcc option missing in my Outlook version?
If the Bcc option is missing, you may be using a simplified view or a specific version of Outlook that hides advanced fields by default. Ensure you are in the ‘Compose’ window. If using Classic Outlook, check the ‘Options’ tab in the ribbon to toggle the Bcc field visibility.
