task in one note doesn`t synchronise with microsoft to do after switch in ms to do

I have the following question about linked tasks in onenote with microsoft to do.

If you create tasks in one note (as an Outlook task), it appears in microsoft to do under tasks.
If you assign this task to a list in microsoft to do, this task loses the link to microsoft to do in onenote .
This means that if you set the task  in microsoft to do  as finished, the task is still displayed as open in one note. the task isn`t able to synchrononisate with microsoft to do any more.

i hope you understand my questition.

thanks
