Furthermore, what is the purpose of BCC in an email system?

Cc means carbon copy and Bcc means blind carbon copy. For emailing, you use Cc when you want to copy others publicly, and Bcc when you want to do it privately. Any recipients on the Bcc line of an email are not visible to others on the email.

Likewise, what happens when someone replies to a BCC? If all your recipients are listed under Bcc:, then none can see or be aware of the others. If any recipient clicks Reply All, the reply will NOT go to anyone they can't see. Remember they can see any name that's listed under To: or Cc:, so be careful with mixed addressing.

Secondly, how do I use BCC in email?

Show, hide, and view the blind carbon copy (Bcc) field

1. Create a new email message or reply to or forward an existing message.
2. If the message you're composing opens in a new window, select Options > Bcc. If the message you're composing opens in the Reading Pane, select Bcc from the ribbon.
3. In the Bcc box, add recipients, compose the message, and choose Send when done.

Is BCC really hidden?

BCC stands for “blind carbon copy.” Unlike with CC, no one but the sender can see the list of BCC recipients. However, the BCC list is secret—no one can see this list except the sender. If a person is on the BCC list, they'll see only their own email on the BCC list.
