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

After you turn on the Bcc box, it appears every time you create a message until it's turned off.

Create a new email message, then click Options > Bcc.
In the Bcc box, add recipients, compose the message, and choose Send when done.

Turn off Bcc

You can turn off the Bcc box for future messages at any time.

Create a new email message, then choose Options >Bcc.

Note: The background color distinguishes between the Bcc button being turned on or turned off. A dark background means the button is turned on, and a light background means it's turned off.

View Bcc recipients

If you're the recipient of a message, you can't see whether the sender added Bcc recipients. Only the sender of a message can see the names of Bcc recipients by opening a message in the Sent Items folder where all sent messages are stored by default.

In the Sent Items folder, open the message that you sent.
In the Reading Pane, view the header section of the message.
Tips:
- If there are more recipients, you'll see the number of recipients and more. In the screenshot, for example, 11 more signals there are 11 more recipients listed in the Bcc box.
- Click more to expand (open) your the message header section.
