Outlook: Offline settings "Days of email to save" admin policy

🚨 The Signal: Admins can now centrally define and enforce the 'Days of email to save' setting for Outlook offline caches. This improves data retention control and reduces local data exposure risks for Australian government users.

The Impact

Security teams and tenant admins are affected, gaining a new control to reduce the risk of sensitive data exposure on end-user devices.

• Security Teams: Reduced risk of sensitive data exposure on compromised endpoints.
• Tenant Admins: New policy control to enforce data retention settings.
• End Users: Offline email availability may be restricted based on policy.

The Action

1. Review existing data retention policies and determine appropriate 'Days of email to save' values.
2. Navigate to the Microsoft 365 admin center or Intune to configure the new policy.
3. Define the default value for 'Days of email to save' and user modifiability.
4. Communicate changes to end-users regarding offline email availability.
