How to import a shared folder with tasks/to do´s in Office 2011 for Mac? How to import To Do´s which were sent by colleagues?

Dear Community,

I can not import folders with To Do´s and neither single To Do´s from my colleagues. Do you have a clue how I can do this? Where is it in the menu bar?

With the windows version it is possible.

Thanks a lot for a litte help!
