How to Fix Microsoft Loop Task Lists Not Syncing with Planner and To Do

To fix Microsoft loop task lists not syncing with planner and to do, first identify the correct account, file, device, or service context. The steps below isolate the cause and apply a result you can verify.

Confirm the Account, Product, and Expected Result

Start by confirming whether the symptom affects one file, one device, one account, or the service itself. That distinction determines whether the next action belongs in the desktop app, the web portal, or an administrator console.

Quick Supported Workflow

First, open the Loop task list component and confirm that Loop, Planner, Teams, OneNote, and Microsoft To Do are signed in with the same work or school account. Next, open the task list in Loop and verify that each task has a title, an assignee, and a due date; only tasks assigned to the signed-in user should appear in the user's To Do list, and verify the final state before changing any backup or secondary account.

Why This Can Happen

• The wrong personal, work, school, billing, or administrator account is selected
• A license, permission, connection, file rule, or local setting does not match the requested action
• Cached credentials or an incomplete synchronization or activation state hides the current server status
• The Microsoft service or application requires a more specific control than a generic restart
