I am having this strange issue, where one mail address in our organization seems to have an automatic cc to another, but I cannot find where it is coming from.
Anytime someone (internal and external) mails to firstname.lastname@example.org, there is a cc to email@example.com even though the sender did not do that. I looked at firstname.lastname@example.org's Mail Flow Settings, but delivery options only forwards this mail to outside email address (email@example.com) and to itself, no reference to betty. Hub Transport in Organization Configuration has no Transport or Journal Rules that has any cc'ing to betty, firstname.lastname@example.org mailbox itself has its own Full control or Send As Permission, there is no distribution group that has both as members.
I think I have looked everywhere I can think of, but still cannot resolve this issue. We are using MS Exchange Server 2008.
