When Outlook receives an e-mail I get this error message.  Any ideas why?
I have some links to notes in Evernote or Omnifocus. When I copy the link and paste it into the body of a Calendar reminder for example, some show up in color and underlined (so that clicking on them runs the appropriate program and opens the file) while others paste as plain black text and are not "clickable". What determines this? I want them all to be clickable. How do I make a link like

omnifocus:///task/lsMswqVSd78

    paste as clickable link into Outlook?
