Outlook for iOS and Android: Send Availability feature to be retired

What and Why: We're retiring the Send Availability feature in Outlook for iOS and Android. This change aligns with ongoing efforts to simplify mobile email experiences and focus on core productivity workflows. Users can continue to share availability by referencing their calendar and including available times directly in email responses. Rollout Schedule: General Availability (Worldwide, GCC, GCC High): We will begin rolling out in mid-July 2026 and expect to complete by late July 2026. Impact on Your Organization: Who is affected: All Outlook users on iOS and Android devices Platforms/Services: Outlook for iOS Outlook for Android What will happen: The Send Availability feature will be removed from the Outlook mobile compose experience.

Users can still check their calendar and manually include available times in email responses. This change is enabled by default; there is no admin configuration or override. Action Required/Recommendations: No admin action is required. Inform helpdesk and support teams about this change. Update any internal documentation or user training that references the Send Availability feature. Advise users to use their calendar to determine availability and share times manually in email replies.
