title: Digitally signed macro is being disabled despite assigning self-signed certificate
body: <p>I have created a self-signed digital certificate for a macro I have built, using the selfcert.exe application in the Microsoft Office directory. I apply the certificate and then close Outlook - from what I understand, I should get a security prompt upon re-opening Outlook that allows an option for 'Enable all macros by this publisher'.</p>
  
  <p>I never get this prompt, and when trying to run the macro, I get a message that it is disabled - despite having the macro security settings set to <strong>'Notifications for digitally signed macros, all other macros disabled'</strong>.</p>
  
  <p>Why doesn't Outlook think that the macro is digitally signed? It is visible if you navigate to Tools -> Digital Signature on VBA.</p>
  
  <p>I suspected it might be something to do with the certificate not being listed as a 'Trusted Publisher', but I have tried copying the certificate over to the Trusted Publishers/Trusted Root certificate directories under certmgr ('Manage user certificates' in Start menu) and this hasn't made a difference.</p>
