I'm using Outlook 2010 but my buddy, using Outlook 2003, doesn't seem to be able to see it either.

I know that if I open the email (external to viewing pane) and go to the [File] tab, then hit the [Properties] button, I can view the contents of the "Internet headers" but that doesn't have BCC information in it.

According to section 3.6.3 in RFC 2822 (internet standard for e-mail messages) there are three ways in which the "Bcc:" field should be implemented:

  1. when a message containing a "Bcc:" field is prepared to be sent, the "Bcc:" line is removed even though all of the recipients (including those specified in the "Bcc:" field) are sent a copy of the message.

  2. recipients specified in the "To:" and "Cc:" lines each are sent a copy of the message with the "Bcc:" line removed as above, but the recipients on the "Bcc:" line get a separate copy of the message containing a "Bcc:" line. (When there are multiple recipient addresses in the "Bcc:" field, some implementations actually send a separate copy of the message to each recipient with a "Bcc:" containing only the address of that particular recipient.)

  3. since a "Bcc:" field may contain no addresses, a "Bcc:" field can be sent without any addresses indicating to the recipients that blind copies were sent to someone.

Which method to use with "Bcc:" fields is implementation dependent, but refer to the "Security Considerations" section of this document for a discussion of each.

If Outlook's implementation is based on the 1st way then I guess I'm SOL. Does anyone know if this the case?

If you can view the raw message (view details and properties of the email) you should see a line like "Envelope-to: bccrecipient@example.com" with your BCC address.
