I upgraded to a nes SBS 2011 Server with Exchange 2010, All the clients connect to the new server and connect to Exchange, all of their emails from Exchange 2003 are imported. When I try to send a new email and type a letter in To the autocomplete populates the name and I then send the email it is returned immediately. If I delete the autocomplete name and then type the email address the email goes thru. That would be OK if I only had one computer but I have 65 and all are doing the same thing. How do I fix this?
