I currently run a 2010 exchange server,
I have two user that complain that their emails get automatically forwarded to another user.
For one person every email they send is cc'd to the third person but only random emails from the second user are cc'd to the third person.
I have checked for rules on both users outlook and owa systems, but none have been set.
I have also checked on the exchange server configuration transport setting but again no rules have been set there either.
The original mail recipient does not know that their mail has been forwarded and neither does the original sender.
The mail on the third person has no headers only stated that it has been autoforwarded
Any ideas would be good as people are now worried about email security
Thanks in advance
