I have Outlook open. In Firefox, I click a mailto: link. Instead of opening a new message, it opens up a new instance of Outlook, which doesn't work.
My problem is basically exactly as described in KB312346
Unfortunately, the solution presented is not for Windows 7 and I can't figure out how to add the -c IPM.Note /m "%1" part of the application string.
In the Tools > Options menu, I have mailto: set to use Outlook, but in the application details, it lists just C:\Program Files (x86)\Microsoft Office\OFFICE11\OUTLOOK.EXE. How do I add the extra settings to that?
