Dragging from Planned to List and "Find Related"

Hi,

I have tasks/emails organized in lists. I initiate them by flagging them with a date in outlook, they appear in To-Do as Flagged emails, which i drag into my lists. 

1. Some are tasks/emails are overdue and i can find them in the "Planned" Area. However, if i want to move it to a List, i can't. Please enable dragging from Planned to Lists. 

2. Since all my tasks are emails, I want to "find related emails", although i can open in email , i can't "find related" so i dont know if it was answered already. Please enable this option in the individual email of office 365 or from within To-DO.
