Updated December 16, 2025: We have updated the timeline. Thank you for your patience. 

Introduction

We are updating the multi-select toolbar in Outlook Mobile. This change will allow users to customize the order and placement of toolbar actions when selecting multiple emails. Users can now Move to Other, Report Junk, Ignore, Pin, and Snooze multiple messages at once.

When this will happen:

• General Availability (Worldwide, GCC, GCC High, DoD): Rollout will begin in early mid-January 2026 (previously mid-December 20252025) and is expected to complete by mid-February 2026 (previously late January 2026.January).

How this affects your organization:

• Who is affected: Users of Outlook Mobile.
• What will happen:
  • Users will be able to customize the multi-select toolbar.
  • No admin action is required.
