How To Enable BCC In Outlook: Complete Step-by-Step Guide
The Blind Carbon Copy (BCC) feature in Microsoft Outlook allows you to send an email to multiple recipients without revealing their email addresses to one another. Enabling and utilizing this field takes less than a minute across the desktop, web, and mobile versions of Outlook, protecting recipient privacy and preventing email chain spam.
Prerequisites and Outlook Version Assessment
Before altering your email composition settings, you must identify which version of Microsoft Outlook you are currently running. The user interface varies significantly between the classic desktop application, the modern Outlook for Windows client, Outlook on the Web, and mobile apps.
- Required Tools & Access: An active Microsoft 365 subscription, Outlook desktop client (versions 2016, 2019, 2021, or Microsoft 365), or internet access for web-based mail.
- Prerequisite Knowledge: Basic familiarity with email composition menus, ribbon navigation, and recipient address field distinctions (To, CC, BCC).
- Estimated Setup Duration: Under 2 minutes for any platform.
Step-by-Step Procedure to Display the BCC Field
Step 1: Open a New Message or Reply Window
Launch your Outlook client and click on the New Email button located in the top-left corner of the Home tab, or open an existing message to reply or forward. This action opens the standard message composition window containing the To and Subject lines.
Step 2: Navigate to the Message or Options Ribbon Tab
Look at the top horizontal menu bar within the open email composition window. Depending on your specific Outlook version, click either the Options tab or the Message tab to reveal the extended toolbar controls.
Step 3: Locate and Toggle the BCC Button
Scan the ribbon commands for the Show Fields group. Click the BCC button. Once selected, the BCC field will immediately appear below the CC field in your current message header and remain visible for all future emails composed on that platform.
Pro-Tip: In the classic Outlook desktop client, you only need to enable the BCC field once per profile. It will persist across all subsequent new messages until manually disabled.
Step 4: Add Recipients to the BCC Field
Click inside the newly revealed BCC text box and begin typing the email addresses or names of your recipients. You can also click the BCC button directly to open your Global Address List or Contact Contacts folder for batch selection.
Warning: Always double-check your recipient placement before clicking send. Moving an address from BCC to CC accidentally will expose that recipient's private email address to every other person on the distribution list.

Troubleshooting Missing BCC Fields and Display Errors
- Root Cause: The Outlook ribbon configuration was reset during a recent Microsoft 365 software update or profile synchronization.
- Actionable Fix: Re-open a message composition window, navigate back to the Options or Message ribbon, and click the BCC toggle button to restore visibility.
- Root Cause: Using an outdated desktop client build that lacks modern ribbon categorization or unified web settings.
- Actionable Fix: Update your Microsoft 365 suite by navigating to File, Office Account, Update Options, and selecting Update Now.
- Root Cause: Draft templates saved before enabling BCC do not inherit the new field automatically.
- Actionable Fix: Delete the outdated draft template, enable the BCC field in a fresh message window, and save that new message as an Outlook Template (OFT format).
Frequently Asked Questions
Can recipients see who was BCC'd on an Outlook email?
No. Recipients placed in the BCC field are completely hidden from anyone in the To, CC, or BCC fields. They receive the email normally, but their address header will not display their inclusion to other recipients.
Does the BCC field work when replying to all?
No. If a recipient who was originally placed in the BCC field hits "Reply All," their response will only go to the sender and visible recipients, protecting their hidden status. However, if they hit "Reply" to the sender alone, only the original sender sees it.
Why does the BCC field disappear when I open a saved draft?
Certain older versions of Outlook do not save field visibility states inside local draft files. If you notice this recurring, ensure your client is updated to the current monthly enterprise channel release of Microsoft 365.
Can I set BCC as the default view for every new email automatically?
Yes. On desktop clients, once you click the BCC button in any open message window, the setting writes to your local profile registry and stays enabled for all future drafts automatically.
