  1. Hi,

    I want to set a transport rule in my Exchange 2013 where every e-mail comes to a recipient will be CC to the recipient’s manager.

    How to do that?

    Thanks a lot for the answer.



  2. Thanks! I couldn’t figure out the field names (I was using field names with spaces which didn’t work).
