When you receive an email notification for a task assigned to you in Microsoft Planner, the link provided typically directs you to the entire plan rather than the specific task. This is a known behavior in Planner, as it does not currently support direct linking to individual tasks within the project. This differs from Microsoft Project, where such direct links were possible.
If you want to access the specific task, you may need to navigate through the plan to find it manually. Additionally, ensure that your users have a product license that includes Exchange Online, as this may affect email notifications and functionality related to tasks in Planner.
