The BCC (Blind Carbon Copy) field enables you to sent mail to multiple targets without the list of recipients being displayed. This is particularly useful if you have an email that has to be sent to a number of your friends or colleagues. At least you can sent the mail knowing that whoever receives it will not know who else the mail has been sent to.
To enable the BCC field in Windows mail proceed as follows:
1/ Open Windows Mail
2/ Click the Create Mail button on the main toolbar
3/ The New Message window will now open
4/ In the New Message window click on View on the main toolbar and, from the drop down menu, select the All header option
5/ The BCC dialogue box should now appear in your email window
