Is there a way to see if an email was also blind carbon copied to someone in an Exchange environment?

I have a coworker who has a history of trying to make other people look bad to make herself look good.  Right now there is a position within our company that we both applied for and I am clearly more qualified because I have the education and experience the job calls for and she has neither.  So lately she has been sending me emails explaining how to do things that are very easy to do and she knows I know how to do them, but she words them as if I don’t know how to do them.  I suspect she is bcc these emails to our supervisor (this is the supervisor who will be hiring for this new position) to make me look bad.  I don’t need to see who she is bcc these emails to, I just want to know if they are being bcc.  I do have administrative access to our Exchange server, but I will not do anything that would be against our work rules.

Thanks in advance!
