i need to know how to change the email setup for all users in exchange 2007 SBS. When the server was configured it would not let me change the email to .com it kept it as .local. Email routes out but unless i can change the users email address to .com no email will route in. i need to get this resolved before monday if possible. The system is a SBS 2008 server running exchange 2007. As it stands now all user email addresses are (email@example.com) and they need to be (firstname.lastname@example.org). Any help will be appreciate.
