Updated December 4, 2025: We have updated the timeline. Thank you for your patience. 

[Introduction:]

To help users declutter their calendars, Outlook Mobile now supports hiding declined meetings. This aligns with existing functionality in New Outlook and Outlook for the Web, where users can choose to show or hide declined events. With this update, users can enjoy a simplified calendar experience across devices.

[When this will happen:]

General Availability (Worldwide, GCC, GCCH, and DoD): Rollout begins in early January 2026 (previously early December 2025) and is expected to complete by late January 2026. 

[How this affects your organization:]

Who is affected: Users of Outlook Mobile who have enabled “Show declined meetings” in New Outlook or Outlook for the Web.

What will happen: 

• Users will see a new setting in Outlook Mobile to hide declined meetings: 



• This setting provides a cleaner calendar view by removing declined events.
• The feature respects existing preferences set in New Outlook or Outlook for the Web.
• No changes to admin policies or configurations are required.
