Inbox not up to date on Samsung 5 mobile phone

Hi there,

I touched something on my hotmail account (Outlook Mail) that I access from my phone, and now all I get in my inbox is emails from years ago. I have tried to find a way to bring my current up to date emails in my inbox back but have had no success. I can still access all my current emails in my inbox on my computer, this is only on my phone. At the top of the page it also does not have the settings logo so I can at least have a look at that. My junk mail box is still up to date. I would appreciate any help you can give me, thank you.....
