Hi, User1 has email addresses user1@domain.com (default), test1@domain.com and test2@otherdomain.com. When emails are sent to test1@domain.com and test2@otherdomain.com, they arrive in user1's inbox, but Exchange 2007 SP1 changes the "TO" field to his default email user1@domain.com. How can the user differentiate which emails were sent to which email address? This never happened on Exchange 2000. How can I stop this from happening? Thanks in advance, ED.
