Microsoft project management software used to plan, manage, and communicate a project schedule and other information among workgroup members, project managers, and other stakeholders.
Regarding your issue, may I kindly ask what are you hoping the "Link to plan" feature will do for you?
- Do you want it to copy your Project schedule into Planner, create tasks in Planner from your Project plan, or keep the two in sync so updates flow automatically?
- When you try the feature, is the option greyed out, missing, or showing an error?
The built-in "Link to plan" feature may not do what it appears to. Even when it's enabled and working, it doesn't sync anything it only adds a shortcut link on a Project task that points to an existing Planner plan. It doesn't copy tasks into Planner, create tasks, or keep the two updated in either direction, and each Project task can only link to one plan.

It may work in one setup and not another because the feature relies on Project being connected to Project Online (Project Web App). Without the right subscription and environment in place, the option won't appear or work at all.
A couple of things worth keeping in mind for the long term. There's currently no built-in way to sync Microsoft Project Desktop with Planner. Project is designed to work with Project Online, and Microsoft treats Project and Planner as separate products. On top of that, Project Online is scheduled to retire on September 30, 2026, so this isn't a reliable feature to build a long-term workflow around.

Hopefully it clears thing up and if you have any other questions or need further assistance, feel free to ask.
