If you use client side CDO 1.21 (installed from the Office CD) you will get
security prompts. I would use server CDO 1.21 (installed when ESM is
installed) and use a mailbox profile logon that has permissions to SendAs
whatever email address you want to use.

There are samples of creating logons like that using CDO 1.21 at
www.cdolive.com/cdo5.htm.

Depends on what you mean by "logged onto server"? What kind of server? If
all you want to do is send messages, Extended MAPI and CDO 1.21 are not
the best choices for API. CDO for Windows would be better.

I mean interactive logon. I have app that runs as a service. Nobody need
to
bee loged onto server.
This app has ability to generate mail using simple MAPI or CDO by
connecting to Outlook profile. App vendor say that if I want to use
sending
mail by simple MAPI or CDO, that there must be user looged on server,
otherwise it would not work.
