Resolving the problem
In Exchange 2010, the Default Authentication Method has changed for the POP3 and IMAP server.
The Default Authentication Method is now to use TLS ( Transport Layer Security ) Authentication which is not supported by Maximo.
The POP3/IMAP server must be reconfigured to use Basic Authentication to allow Maximo to access the mailbox. [IBM Support]
