The "mapimail" class from nbcsoftware comes with with fox.reg registry file that add a licence registration to enable the class to be used. It may fix your problem.

>the username of the email is "ABC", and as the user who login Window ME, the username is "1234", Does it related to the problem ?

The MAPI user name is the name of the profile not the PC user name. So they are not the same.
