When you use an Internet Message Access Protocol (IMAP) e-mail client to view a message that was sent from an Exchange Server computer, you may notice that attachments are not visible. You can view the attachments correctly with Messaging Application Programming Interface (MAPI) and Post Office Protocol version 3 (POP3) clients and Microsoft Outlook Web Access (OWA). This issue affects messages that are sent to another Exchange Server site by site connectors or X.400 Connectors. Recipients in the site can see the attachments properly.
