We have en exchange2003 and will migrate lather on 2010;
We have many version of Outlook on the domain ( 2003, 2007 & 2010 );
Some people for different reason can make errors when they are sending or answering emails to externals people (other domain name address ).
I would like to find a solution to implement an "outgoing mail control" on all emails to be sure that our users will realize that one email is going to a people "outside" of our company.
The result could be that a specific "color" or " flag" or many other indication to make that kind of emails "SPECIFIC" to advise quickly the user that he is "sending" an email to an other company user... (??)
