Do I have to sync all tasks in a project to Planner, or can I choose which ones?
Similar to selecting which projects to sync, every task has a sync option which you can turn on or off.
Will Project recognize when users update tasks in Planner?
Yes, the sync will allow changes from both Project and Planner to sync back and forth.
How do I get Project and Planner integration capability?
To get the integration capability, you need to subscribe to either Project Online Professional or Project Online Premium. For Planner, you need to subscribe to Office 365 Business Essentials, Business Premium, E1-E5, or an Education plan. Contact us with any questions.
