Introducing Calendar Agent capabilities in Microsoft 365 Copilot

Microsoft 365 Copilot introduces Calendar Agent capabilities to automate calendar management via natural-language instructions, helping users accept, follow, decline, or delete meetings. Rolling out late April to early May 2026, it respects existing policies, user settings, and compliance, with no new admin controls added. We’re introducing Calendar Agent capabilities in Microsoft 365 Copilot to help users reduce meeting overload and automate routine calendar decisions. With natural-language instructions, users can allow Copilot to automatically accept, follow, decline, or remove canceled meetings based on rules they define. This capability builds on existing Copilot agent controls and respects current tenant compliance and governance settings, while helping users save time and stay focused. When this will happen Rolling out to Frontier: Rollout start: Late April 2026 Rollout end: Early May 2026 How this affects your organization Who is affected Users with a Microsoft 365 Copilot license using: Outlook (classic and new) Outlook on the web Microsoft Teams Outlook mobile (iOS and Android) IT admins who manage Copilot agent access and policies in Microsoft 365 What will happen Calendar Agent capabilities will appear in Microsoft 365 Copilot Chat from calendar-related surfaces. Users can enable agent actions by selecting Allow Actions (Frontier) in Copilot Chat. Users can create ongoing, natural-language calendar instructions (for example, “Always accept meetings from my manager if my calendar is free”). Calendar Agent respects each user’s Outlook working hours settings.

Calendar Agent acts only on the signed-in user’s calendar and does not operate across mailboxes or tenants. What is not changing: Existing admin policies, permissions, retention, and compliance boundaries remain unchanged. No changes are made to data residency, audit logging, or Purview enforcement.
