Hi all, this is a repost. My problem is this: i have SBS2003 with exchange 2003 configurated to download internet message from external server. Local Domain is named mycompany.local and external domain (internet) mycompany.com. One of the users of the lan work with a notebook. He have not mailbox in local exchange domain but have mailbox in external server domain. But when other users try to send message to this user it come back with error. The error show only that the address is not in the domain. How can I solve this problem? PLEASE help me. Thanks. C
