New meeting response option: decline and propose a new time in Outlook Mobile [MC1269213]

Message ID: MC1269213

[Introduction]

We’re introducing the ability for users to Decline and Propose a New Time when responding to meeting invitations. This update improves scheduling clarity by allowing recipients to explicitly decline a meeting while still suggesting an alternative time.

This update is applicable to Outlook for iOS and Android only; other platforms already include this feature.

[When this will happen:]

General Availability (Worldwide, GCC, GCCH): Rollout begins mid-April 2026 and is expected to complete by mid-May 2026

[How this affects your organization:]

Who is affected:

• All Microsoft 365 users responding to meeting invitations in Exchange Online–based calendar experiences (for example, Outlook on the web, desktop, and mobile).
• Worldwide, GCC, and GCC High tenants

What will happen:

• A new Decline and Propose a New Time option will be available



• This option appears alongside existing responses such as Tentative and Propose a New Time
• When selected, the meeting is declined and an alternative time suggestion is sent to the organizer
• The feature is enabled by default
• Existing meeting policies and workflows are respected; no policy changes are required

[What you can do to prepare:]

• No admin action is required. 
• Consider updating internal documentation or training materials that describe meeting response behavior

[Compliance considerations:]

No compliance considerations identified, review as appropriate for your organization.
