Problem: User needs hard copy of sent mail in BCC field
Open e-mail you want to print,
Tools - Forms - Design this form (this will not appear if you open it from Outlook menu itself)
From Field chooser select from drop-down menu "Address fields"
and then drag BCC to e-mail , below CC.
Then right-click BCC - Properties - and in Validation tab, check the option "Include this field for Printing..."
Save, close and then BCC will appear when printing this mail.
