I am just starting to use BCM so this is a basic question.
I want to send a marketing campaign email using the BCC field for my
distribution list. But the Options field that says "show bcc" is deliberately
greyed out and unusable.

This seems to be a very typical need -- if I send a campaign to my client
list, I don't want them all seeing each other's emails.

So how do I do this?

On a less important note, BCM also doesn't give me the option of sending
from a specific account. I use my Outlook to access several email addresses;
for my main business, for personal, and for a secondary business. BCM uses
the primary account to send the campaign -- so I have to change it to the
account I want to use (and if I forget to reset to my normal settings I risk
sending an email through the wrong account)

TIA
