Outlook: Entry point change - apps when reading emails moved to the ribbon

🚨 The Signal: Outlook's 'Apps' entry point is moving to the ribbon in New Outlook and Outlook for Web. This is a user interface change, not a security control change, and does not alter app permissions or access.

The Impact

End users are affected by a minor UI change; no direct security risk is introduced or mitigated.

• End users: May need to re-learn where to click for Outlook add-ins.
• Admins: No security configuration changes are required.
• Security Team: No new attack vectors or vulnerabilities are introduced.
• Compliance Officers: No changes to data handling or access controls.

The Action

1. Communicate the UI change to end-users via internal channels.
2. Update any internal user guides or training materials that reference Outlook add-in locations.
