Outlook Mobile Send Availability Return Planned for October 2026, Not Yet Launched

A return after a planned retirement​

This is not a new scheduling feature appearing out of nowhere. In a Microsoft 365 Message Center notice published June 16, 2026, Microsoft said it would remove Send Availability from the Outlook mobile compose experience, beginning in mid-July and expecting to finish by late July. The notice said users could still consult their calendars and type available times into an email; calendar functionality itself was not being removed. The notice is preserved in the Microsoft 365 Message Center Archive as MC1393802.

Microsoft’s Outlook mobile release notes offer another useful reference point: a September 2024 Android update described Send Availability as an existing action in the email compose toolbar. The newly planned return is therefore about restoring a familiar way to share times from a draft, not introducing the concept of availability sharing to Outlook mobile. Those older release notes do not establish what the restored interface will look like.

What the roadmap does—and does not—promise​

The new entry names both iOS and Android, but calls out the keyboard and VoiceOver improvement specifically for iOS. It does not identify which controls will gain better access, describe an equivalent Android change, specify a minimum app version, or announce a new admin setting. Nor does it explain why Microsoft changed direction.

Its cloud scope is Worldwide (Standard Multi-Tenant). That distinction matters: the earlier retirement notice also named GCC and GCC High, but the return entry does not promise those government environments the same October timetable.

Most importantly, the item remains In development. Microsoft’s roadmap guidance distinguishes that status from Rolling out, when production deployment begins, and Launched, when deployment is complete. October is a planning date, not proof that the option has reappeared on every phone.

For IT teams, the practical move is modest: keep the manual-calendar workaround in helpdesk guidance for now, then confirm the option in your organization’s iOS and Android Outlook apps when rollout begins. If users ask where Send Availability has gone—or when it will return—the answer should reflect the two separate announcements, not assume that a roadmap date has already put the button back.

Update: Send Availability is now rolling out to Outlook mobile (October 10, 2026)​

Microsoft has restored Send Availability in Outlook for iOS and Android, according to Neowin’s report on a new Microsoft 365 Admin Center notice, MC1493186. The feature is available while composing an email reply: users can select the calendar icon and choose Send Availability to insert free times without leaving the draft.

The report also says no administrator action is required. On iOS, Microsoft is again calling out access through the on-screen keyboard and VoiceOver, matching the accessibility commitment previously listed on the roadmap.

This supersedes the earlier October planning status: the option is now reported as available rather than merely in development. Organizations should update Outlook mobile where necessary and verify availability on managed Android and iOS devices.

Update: Microsoft marks Send Availability as rolling out (October 20, 2026)​

Microsoft has updated roadmap item 570665 to Rolling out, replacing its previous in-development status. The return of Send Availability is now actively deploying to Outlook for both iOS and Android in Worldwide Standard Multi-Tenant environments.

The roadmap continues to list general availability for October 2026 and confirms the iOS accessibility enhancement for keyboard and VoiceOver users. This is a rollout status, not confirmation that every tenant or device has received the feature; organizations should continue checking updated Outlook mobile clients as deployment progresses.
