[When this will happen:]

General Availability (Worldwide): We will begin rolling out late May 2025 (previously early May) and expect to complete the rollout by early June 2025 (previously mid-May).

[How this will affect your organization:]

Before this rollout: Users can only skim and scroll though their Copilot chat sessions to find a desired session.

After this rollout: Users will be able to type keywords to search their chat sessions. As a user begins typing, session results will appear based on the keyword(s), and users can select the session that corresponds to their search.

This change will be on by default.
