MC846387 - Microsoft Outlook: Replace quick compose pop-up with inline appointment creation in new Outlook for Windows and web

Updated December 12, 2025: We have updated the timeline. Thank you for your patience.

In new Outlook for Windows and web, when single-clicking on an empty time slot on the calendar surface, the quick compose pop-up will no longer appear. Instead, you will be able to create an appointment by typing directly in the time slot on the calendar grid, just as you can in classic Outlook for Windows. There will be no change to double-click behavior; the full compose form will still open as it does today.

This message is associated with Microsoft 365 Roadmap ID 406948.

When this will happen:

Targeted Release: We will begin rolling out early October 2025 (previously early April) and expect to complete by end of February 2026 (previously late October 2025).

General Availability (Worldwide): We will begin rolling out early November 2025 (previously early May) and expect to complete by end of March 2026 (previously late November 2025).

How this will affect your organization:

This may affect how users create appointments quickly on the calendar surface. We expect this to be a better experience, especially for those familiar with classic Outlook inline appointment creation.

This update is available by default.

What you need to do to prepare:

This rollout will happen automatically with no admin action required. You may want to notify your users about this change and update any relevant documentation.
