Thank you very much , Sue.Unfortunately,I've installed Outlook 2000 in IMO
mode,and ,of course,there's no such things like Exchange Server.Any other
ways?

You'd have to use CDO or Redemption. I think this sample will help:

There is a "send plain text only" checkbox on the contact form,but it
appears that there is no equivalent property in the Outlook Object
Model,how
can I check or uncheck it programmatically?
Thanks in advance.
