I can't access my email on my computer. I can only read on my iphone?

Hi - I can only see my email on my iphone. When I try and access on my pc it is just blank. I'm unable to compose a message or see any messages. Please can you help?

This may just be the version of your pc, maybe you need to update a feature the email system works on. With the iPhone, the email would be designed for it and would usually be updated with apples updates every once in a while so you don't need to do it separately
