The requested mailbox is not available on this server. CAUSE ===== A custom recipient object on a Microsoft Exchange Server computer does not have a physical mailbox associated with it. Therefore, it is not possible for a POP3 or IMAP client to access a custom recipient object on a Microsoft Exchange Server computer. This behavior is by design. MORE INFORMATION ================ None of the protocols listed on the Protocols tab of a custom recipient object can be used to access a custom recipient.
