Outlook 365 email body/content not showing

I don't know if any of you have tried this or not. Try opening your email on your smart phone or device. E-mails not seen on my desktop i can see on my smart phone. This is why i am on here looking for a solution. I get alot of e-mails that i can not see on my Windows 10 outlook, but i can see them on my smart phone. I am still waiting to find out what formatt these sender are useing. Maybe i am missing something in my settings of my outlook 365.
