Am alternative approach I found was to Self Sign the script for use on
my computer - allowing me to keep my security settings.

See
http://www.microsoft.com/technet/pro.../vbamacro.mspx
for full details.

The basic approach is to use C:\Program Files\Microsoft
Office\OFFICE11\selfcert.exe to create the digital signature and then
select this inside Outlook.

Hope this is of use to people.
