Vulnerability discussion

This policy setting controls whether hyperlinks in suspected phishing e-mail messages in Outlook are allowed. If you enable this policy setting, Outlook will allow hyperlinks in suspected phishing messages that are not also classified as junk e-mail. If you disable or do not configure this policy setting, Outlook will not allow hyperlinks in suspected phishing messages, even if they are not classified as junk e-mail.

Procedure: Use the Windows Registry Editor to navigate to the following key: HKCU\Software\Policies\Microsoft\Office\16.0\outlook\options\mail Criteria: If the value JunkMailEnableLinks is REG_DWORD = 0, this is not a finding.

Pro Tips

Lavender hyperlinks in small type off to the right (of CSS class id, if you view the page source) point to globally unique URIs for each document and item. Copy the link location and paste anywhere you need to talk unambiguously about these things.

You can obtain data about documents and items in other formats. Simply provide an HTTP header Accept: text/turtle or Accept: application/rdf+xml.
