Microsoft Copilot (Microsoft 365): Scheduling with Copilot

🚨 The Signal: Copilot can now schedule meetings and appointments directly from chat, including finding times, booking rooms, drafting agendas, and sending invites. This expands Copilot's agentic capabilities and access to user calendars.

The Impact

All users are affected; Copilot's expanded calendar access poses a moderate risk to meeting privacy and calendar integrity.

• End Users: Risk of unintended meeting disclosures or misconfigurations due to AI scheduling.
• Security Team: Need to monitor Copilot's calendar interactions for anomalous behavior.
• Admins: Must ensure Copilot access to calendar data aligns with organizational policies.
• Compliance Officers: Review Copilot's scheduling actions against data privacy requirements.

The Action

1. Review and enforce Microsoft 365 Copilot access policies in the Microsoft 365 admin center.
2. Audit Copilot's permissions to Exchange Online mailboxes and calendars via PowerShell (Get-EXOCopilotsSettings).
3. Implement data loss prevention (DLP) policies in Microsoft Purview to monitor sensitive information in meeting invites.
4. Educate users on responsible Copilot usage for scheduling, emphasizing data privacy considerations.
5. Monitor Copilot activity logs in Microsoft Puril for unusual calendar modifications or access patterns.
