(Updated) Clearer RSVP selection in Outlook Mobile [MC1269211]

Message ID: MC1269211 (Updated)

Updated June 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 end of June 2026 (previously early June) and is expected to complete by end of July 2026 (previously end of 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.
