Updated April 29, 2026: We have updated the timeline. Thank you for your patience.
Introduction
We’re improving the RSVP experience in Outlook Mobile by visually highlighting the response a user has selected (Yes, Maybe, or No). This makes it easier for users to quickly see how they’ve responded to a meeting invitation.
When this will happen:
General Availability (Worldwide, GCC, GCC High): Rollout begins in early June 2026 (previously late April) and is expected to complete by end of June 2026 (previously early June).
How this affects your organization:
Who is affected:
- All users who access Outlook Mobile on iOS or Android
- Applies to Worldwide, GCC, and GCC High tenants
What will happen:
- The selected RSVP option (Yes, Maybe, or No) will be visually highlighted

- Users can quickly confirm how they responded to a meeting invitation and edit as needed

- The feature is enabled by default
- No changes to existing meeting workflows or policies
- No impact to Outlook on the web or Outlook desktop clients
What you can do to prepare:
- No admin action is required; the update will roll out automatically
- Consider notifying helpdesk staff of the visual change
- Update internal documentation if needed
Compliance considerations:
No compliance considerations identified, review as appropriate for your organization.
