Specifying Passwords with Simple MAPI

Whether a password is required for you to log on depends on the operating system which is running on the computer. If the operating system integrates messaging system credential checking into the initial system logon, you need not provide a password to the MAPILogon function. If not, a password is required from the user or from a cache location implemented by the client. Microsoft Windows NT and Microsoft Windows 95 do not require passwords for MAPILogon since the user's initial logon to the operating system suffices for both. Clients running with Microsoft Windows for Workgroups are required to provide a password for MAPILogon.
