Support for disabling file previews in Microsoft Teams

🚨 The Signal: Microsoft Teams now allows users to disable file previews in chats. This user-level setting, on by default, offers individual control over content display, potentially reducing accidental exposure of sensitive information.

The Impact

All Teams users are affected, gaining a minor privacy control with no direct security risk or benefit unless explicitly configured.

• End-users: Can disable file previews for personal privacy.
• Helpdesk: May receive queries about the new setting.
• Security Team: No direct security impact, but awareness is useful for user guidance.

The Action

1. Inform helpdesk staff about the new 'Enable file previews' setting under Teams Settings > Files and links.
2. Optionally, communicate to users that they can manage file previews in their Teams settings for privacy preferences.
