Microsoft Outlook: Link preview retirement

🚨 The Signal: Microsoft has retired the link preview feature in Outlook for Windows and Outlook on the web. This change removes the automatic generation of visual preview cards for web links, reducing potential vectors for social engineering and improving email security posture.

The Impact

All Outlook users are affected by the removal of link previews, which slightly reduces the risk of deceptive link presentation.

• End users: No more visual link previews, reducing phishing risk.
• Security teams: Minor reduction in social engineering attack surface.
• Help desk: May receive queries about the missing preview feature.

The Action

1. Inform users that link preview cards are no longer automatically generated in Outlook.
