I looked into this further and found that many corporate email servers
are set to block emails where the To: field isn't addressed to someone
in the corporate domain. So the BCC trick won't work in many cases.

I looked at the mail merge option. That will work, but I don't want to
have to set it up everytime I send out something. So I've decided to
just write an add-in that will work like mail merge, but all within
Outlook.


Thanks,
Nick
