Microsoft is integrating Planner into the New Outlook sidebar, allowing users to manage tasks without leaving their inbox and signalling a move to make Outlook a central hub for productivity and project collaboration.
Microsoft is rolling Planner into the New Outlook sidebar, giving users a way to handle tasks and projects without leaving their inbox. According to an updated Microsoft 365 message flagging the change, the feature is already reaching some Windows users and should be available more broadly by the end of August 2026. The move reflects Microsoft’s continuing push to make Outlook a hub for daily work rather than just email and calendars.
The integration means Planner can be pinned alongside Microsoft To Do and other Microsoft 365 tools in the left-hand panel. Users will be able to check plans, update tasks and switch between workspaces with less context switching. Microsoft says the change was driven by customer demand for closer ties between task management and routine productivity apps. Handsontek reported that the rollout began in mid-May 2026, is enabled by default and does not require admin action, while existing permissions remain in force.
Microsoft is also signalling that Planner, rather than To Do, is becoming its main task-management layer, especially for collaborative work and larger projects. The company’s Planner documentation describes the service as a unified work-management product that brings together elements of Planner, Project for the web, To Do and Copilot in one interface. Microsoft’s own support material also shows how Copilot in Planner can generate tasks, goals and buckets from prompts, underlining how the app is being positioned as both a planning tool and an AI-enabled workflow surface.
Outlook Classic will not get the same treatment. Microsoft currently has no plan to add Planner integration to the older desktop client, which will continue to lean mainly on To Do for personal task tracking. That fits Microsoft’s wider strategy of keeping Outlook Classic on maintenance while adding most new features to New Outlook. AI is the main exception: Microsoft says Copilot will arrive in Outlook Classic in August 2026, and the company is also continuing to add other changes to New Outlook and Outlook Mobile as it nudges users towards the newer client.
