    Thanks for those advices.
    My service must get e-mail on the exchange server from a windows
    service in order to process data automatically.

    The problem comes from the environment. My Windows service runs on one
    computer and Exchange runs on the other one.

    It is possible to get mail easily from an Exchange Server with WebDav
    and how ?
    (links...?)

    How to resolve the identification problem of a Windows service, what
    is the solution to provide a login and a password to access Exchange
    server without using Windows identification layer ?

    Thanks for help.
