Rollout

Roadmap

Rollout dates are often only in the text. When Microsoft moves them, the change shows under "What changed".

Schedule dates changed in the text

Date phrases in schedule sentences differ between the versions this installation saw
  • Seen 18 Jul 2025 early July 2025 → late July 2025
  • Seen 29 Apr 2025 late April 2025, early May 2025 → late May 2025, early July 2025
  • Seen 28 Mar 2025 late March 2025, early April 2025 → late April 2025, early May 2025, early June 2025

Read from date phrases in Microsoft's text, not from notice metadata. A changed phrase can be a moved rollout, a new milestone or just rewording; "What changed" below shows which.

What the notice says

Microsoft’s text, with source markup removed
Updated July 18, 2025: We have updated the timeline. Thank you for your patience. Updated April 29, 2025: We are making additional fixes which will delay this release. Our updated plan is to make this feature available to Targeted Release customers in Outlook for the Web and the new Outlook for Windows in May, and to Worldwide in June. Copilot Agents are coming soon to both the Web and Work tabs of Microsoft 365 Copilot Chat in Outlook for the Web and the new Outlook for Windows. This change is associated with Microsoft 365 Roadmap ID: 481558  When this will happen: Targeted Release: We will begin rolling out late May 2025 (previously late April) and expect to complete by early June 2025 (previously early May). General Availability (Worldwide): We will begin rolling out early June 2025 (previously early May) and expect to complete by late July 2025 (previously early July). How this will affect your organization: Agents extend the capability of Microsoft 365 Copilot Chat in exciting ways, letting users customize their Copilot experience. From Copilot in Outlook, the right-side panel will show agents that the user has previously installed or that their admin has previously deployed. The panel will also provide entry points to Get Copilot agents in the app store and to Create an agent. What you need to do to prepare: Agents in Outlook will respect the same admin controls as agents in Microsoft 365 Copilot Chat. Admins can manage agents as apps in the Integrated apps section of the Microsoft 365 admin center. Admins can also enable or disable Copilot extensibility for their org, and control who can access agents within their organization.  Review: Manage agents for Microsoft 365 Copilot in Integrated Apps.
