If your office has multiple floors, moving between floors is easy. Simply click on the Map Icon to bring up your office floor plan heads-up display. When you click on the name of the Floor, a drop down box will appear. Simply click the floor to which you want to go and that floor plan will appear. Click on the room or office you want to visit and you will be automatically transported there.
To return to your office, click your home icon on the top left of your screen.
Please note that your Apps will not travel with you to the new floor.
