I have successfully created vbscript which auto sets the importance
level on an Outlook custom form message when a particular item is
selected in a custom combo box.

However, our network security has been upgraded and VB script in
outlook forms is being blocked, so my code will not run.

Has anyone run into this problem?

Can I work around this through a validation formula(ie
IIF(cmbo1="Action",importance = 2, importance=1)
