Why not use a real certificate? Well, obtaining a real code signing
certificate cost around $400. A self signed certificate is free, and also
enables me to get rid of all annoying Security Warning windows in
Microsoft Office and still use the High or Medium security setting.
Ok, lets get started. The following procedure is for Windows 2000 an XP only.
Since I don't have Windows 95/98/Me installed on any of my systems I can't write
an installation instruction for these operating systems. (Do I hear a
volunteer??).
First we have to start the Microsoft Management Console. The easiest
way to do this is by selecting run from the Start Menu and enter
mmc.

Now press Ctrl+m (hold the control key and press m), the Add/Remove
Snap-in window appears. Press the Add button. Now the Add
Standalone Snap-in window appears.

Select Certificates and press Add. In the Next window, make
sure that My user account is selected and press Finish. Now press
Close and Press Ok in the Add/Remove Snap-In window.
Now expand Certificates-Current User and right click Trusted Root
Certification Authorities.

Select Import... from the All Task menu. A wizard starts, press
Next in the introduction screen. Now you can press the Browse
button and select the certificate to import.
You can find the certificate in the Outlook-Sync subfolder of your
program files folder.

Select AvigoOutlook.cer and press Open. Now press Next
to continue with the wizard. Make sure that Place all certificates in the
following store is selected and that the Trusted Root Certification
Authorities certificate store is selected.
Now press Next and Finish. A Window will open, press Yes.
The certificate is now installed.
Next time you start Microsoft Outlook, you can select the Always trust
macros from this source check box and press Enable macros. From now
on you will never be bothered again :-)
