I added a hotmail email address to Recipient Configuration | Mail Contact on Exchange 2007, the email address is abc@hotmail.com. When I select this mail contact abc@hotmail.com from address book in Outlook, it cannot be delivered to Hotmail and no NDR also. However; if I send email to another hotmail email address which is not added to Mail Contact in Exchange 2007 like doggy@hotmail.com, it fine; I can see my email in doggy@hotmail.com mailbox that sent by Exchange 2007 , WHY I cannot send if the hotmail address added to Mail Contact. I added abc@hotmail.com to Mail Contact because abc@hotmail.com is a business partner of company and the user who will send email to this email address frequently. Therefore I added it to Mail Contact for user to locate easier, then they do not need to keep their own contact. Please help. -- Kane
