Create ToDo via sending mail in user's mail box

Hi In my application there are some task assigned for each user. For which i hav to create Task in user’s calendar and todo list.

Now there are to situations

  1. when i have access to user’s mailDatabase – In this case i have successfully created ToDo in his calendar with all required fields(Alarm,categories,…etc).

  2. When i do not hav access to his mail box … The solution i have is to send ToDo via mail. Which also i have done successfully but there is one problem that Category field not get value while i alredy set categories item from backend in that doc before sending.

    Now i got stuck at this point If any one has done similar to this please suggest the solution.

Thanks & Regards

Rohit
