When to Use BCC
The To: field, of course, is all you need to address a message in Windows Live Hotmail.
What if you want to avoid a long list of email address in that field, or need to copy somebody without their address visible to other recipients?
For these needs, you get Bcc: — blind carbon copy. Recipients in this field will get a copy alright, but their addresses are deleted before the message is delivered (to all recipients).
Windows Live Hotmail does not expose the Bcc: field right away, but adding recipients to it is still easy.
Add a Bcc: Recipient to a Message in Windows Live Hotmail
To add recipients to the Bcc: field when composing a message in Windows Live Hotmail:
Click Show Cc & Bcc (right above the To: line and to the right). Type the desired recipient’s email address in the Bcc: field or use the Bcc: button to select people from your contacts. If you add more than one recipient, separate them with semicolons (like: “tina@example. com; tim@example. com”).
Using Bcc: you can also send an email to “undisclosed recipients” from Windows Live Hotmail.
