I had the new type Outlook page but now its reverted to the Classic style page. Whenever i use the mail icon on the quick start task bar i get a pop-up telling me there is a problem with a procedure entry point, when i cancel this three times i get the Classic style Outlook screen with the toggle switch to try the new Outlook but when i do this i am presented with the same pop-up. I can’t now get the new style Outlook screen back.

None of these are Apple products, you'll need to discuss this with Microsoft support.
