I need to send Outlook Appointments and Tasks with out prompting the User for Validation (office2000+). I heard that you can register DLL's as safe (server side)- and the application (or DLL rather) will be able to work it's magic unhindered?

Any Exchange Server Admin's ::
-Will this work.
-How should my Network admins go about doing this, or will they already know how?
-Any additional info that might be useful?

_Thanx a lot guys/gals :-)
