Updated August 4, 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 mid-September 2026 (previously August) and is expected to complete by mid-October 2026 (previously end of August).
[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.
