Assessment Reasoning
The update moves the rollout timeline from late July to end of August through late September 2026, so current planning should reflect this. No configuration changes are needed, but admins should update internal documentation and helpdesk scripts to reference the new Get Diagnostics name and review allowlists to ensure continuity. User impact is minimal as functionality and workflow remain unchanged, with only a label change. Admin effort and urgency are moderate due to documentation and network considerations rather than technical reconfiguration.

Updated July 31, 2026: We have updated the timeline. Thank you for your patience. 

[Introduction]

We’re updating the Collect Diagnostics feature name to Get Diagnostics for Outlook Mobile and Outlook for Mac. Along with this rename, diagnostic logs sent during support interactions will now be routed through the Microsoft 365 diagnostics service instead of the legacy PowerLift service. This change aligns Outlook with other Microsoft clients, simplifying support workflows and providing a more consistent diagnostics experience.

[When this will happen:]

General Availability (Worldwide): Rollout will begin end of August 2026 (previously late July) and is expected to complete by late September 2026 (previously mid-August).

How this affects your organization:

Who is affected:

  • Organizations using Outlook Mobile (iOS and Android)
  • Organizations using Outlook for Mac
  • IT admins maintaining documentation referencing Collect Diagnostics

What will happen:

  • The feature name changes from Collect Diagnostics to Get Diagnostics in Outlook Mobile and Outlook for Mac.
  • Diagnostic logs will be sent to the Microsoft 365 diagnostics service instead of the PowerLift service.
  • There is no change to user workflow or behavior beyond the updated name.

      • Outlook Contact Support
      • Other Microsoft clients such as Company Portal and Microsoft Authenticator
  • No other action is required if *.acompli.net is already allowlisted.
