This newsgroup is intended for questions about Access, the database product
that's part of Office Professional.
Are you trying to send e-mail using Access? If so, are you using the
SendObject command (which does support bcc), or are you using some other
approach?
If you're not using Access, I'd suggest reposting your question to a
newsgroup related to whatever e-mail client you're using. I see that this
question was posted using Windows Mail, so you may want to check out
