How do I sign a script so Outlook will run it without querying it.

I've got a VBS script (below).

When I run it, Outlook XP says that there is another program running, sending email on my behalf.

What I want to do is :

1 - Get a digitial signature.
2 - Sign the script so that Outlook knows that it is from me.
3 - In the script, check that I will be allowed to send email.
4 - Tell Outlook only to allow signed/trusted scripts.

The script is ...

This script is saved as a .VBS file and is ran when my local machine has a new virus update (which happens automatically).

Welcome to the enhance email security update -- who some like to call "hell".

here is the bad news... signing the script will not do anything about that prompt.  your options are the following.

1) you connect to a microsoft exchange or hp openmail system. ask the administrator to implement the admintrative features of this enhancement.  good information on it can be found at:


2) redo your solution using c/c++ (or delphi) and extended mapi.

3) use a 3rd party tool called redemption that allows any com based development language to use the outlook object model w/out incuring the security dialogs

oh darn... one more.

4) if your solution is running on windows 2000 or windows xp box, use cdo for windows 2000 to send administrative smtp alerts. (i do this one for symantec's norton antivirus corporate edition)

Just so you know that what I am saying about digital certs is true, see http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dn_voices_askgui/html/askgui04022002.asp.  You will find a paragraph that states...

There is no way to circumvent Outlook security features using registry keys, digital certificates, or any other mechanism other than that described in the article above.

I don't want to change the security model as this will mean those stupid VBS auto-attachments can run when I don't want them to.

My VBS is actually launched by the our AV updater on a successful update.
