What is bcc in outlook

Last updated: April 1, 2026

Quick Answer: BCC (Blind Carbon Copy) in Outlook is an email feature that allows you to send messages to recipients while hiding their email addresses from other recipients. Recipients in the BCC field cannot see each other's addresses.

Key Facts

Understanding BCC in Outlook

BCC stands for 'Blind Carbon Copy' and is one of three recipient fields available in email composition. When you place someone in the BCC field, they receive a copy of the email, but their email address remains hidden from all other recipients, including those in the To and CC fields. This feature is particularly useful when sending emails to multiple recipients who should not see each other's contact information.

BCC vs CC vs TO Fields

Understanding the differences between recipient fields is crucial for effective email communication. The To field contains primary recipients who are expected to read and respond to the email. The CC (Carbon Copy) field includes secondary recipients who receive a copy of the email, and importantly, all recipients can see the addresses in the CC field. The BCC field functions differently—recipients here receive the email but their addresses are completely invisible to everyone else, including the main recipient and other CC'd individuals.

How to Use BCC in Outlook

To use BCC in Outlook, compose a new email as usual. If the BCC field is not immediately visible, click the 'Cc' button or 'Show Bcc' option to reveal it. Once visible, you can enter email addresses in the BCC field just as you would in the To or CC fields. Recipients added to BCC will receive the email without their presence being disclosed to others. This flexibility makes BCC invaluable for various professional and personal scenarios.

Common Uses for BCC

BCC is commonly used in several situations. When sending emails to large mailing lists, BCC protects individual privacy by preventing everyone from seeing all email addresses. In professional settings, BCC can be used to send updates to multiple employees while maintaining confidentiality about who else received the message. For customer communications, organizations use BCC to avoid revealing customer email lists. Additionally, BCC is helpful when you want to keep someone informed about a conversation without the primary recipient knowing they are being copied.

Privacy and Best Practices

BCC is essential for protecting email privacy and complying with data protection regulations. When you have a large distribution list, using BCC instead of CC prevents the unintended sharing of personal email information. However, it's important to use BCC ethically and transparently. In some professional contexts, informing people that their email is being BCC'd to supervisors or compliance officers is required. Always consider the ethical implications and workplace policies when using BCC, as it should enhance communication without deceiving recipients.
