Outlook 2003 one or more activex controls could not be displayed
A support customer rang the other day as she was receiving this message when in outlook she clicked on new mail.
One or more ActiveX controls could not be displayed because either:
1, Your current security settings prohibit running ActiveX controls on this page or
2, You have blocked a publish of one of the controls.
After having a good look, I found that the security had been changed, I had to go to tools, Options then click the security tab & select Internet from the drop down, Apply & OK.
