No help menu - cant expand

When I rdp to my network, the screen on the iPad is small. I want to have the entire iPad screen used but thats not happening. Theres no help menu that shows what to do to make the full screen be used so its not a useful app because I cant use it properly especially with programs like outlook as theres too many small xs that need to be clicked to open and close emails and the screen is too small which makes it difficult
