M365 Changelog: Planner tasks storage location update

Petri Staff


MC289682 – Updated May 03, 2022: Microsoft has updated the rollout timeline below. Thank you for your patience.

Microsoft is pleased to roll this out after the delay (MC229058 – May ’21). Starting in mid-October 2021, a copy of some Planner tasks will be stored in a user’s Exchange mailbox. All Planner tasks will continue to be stored in the Planner Service.

When this will happen:

  • Standard: Microsoft will begin rolling this out in mid-November 2021 and are targeting completion of the rollout by late January (previously mid-December). – Complete
  • GCC: Microsoft will begin rolling this out in late March (previously mid-January) and is targeting completion of the rollout by late May (previously late April). 

How this will affect your organization:

A secondary copy of Planner tasks which are assigned to at least one user will be stored in the user’s Exchange mailbox. If a task is assigned to multiple users, each user will have a copy of the task stored inside their individual mailbox. Unassigned tasks will not be copied to a mailbox.

For end users, existing To Do, Planner, and Outlook Task experiences will remain the same.

This update supports our work to add Planner tasks to eDiscovery and to build deeper integrations between To Do and Planner.

What you need to do to prepare:

There are no changes to end user experiences for the Planner or To Do apps. Planner tasks assigned to users will automatically start appearing as part of existing eDiscovery experiences.
