Meeting invitees in the Calendar app only show myself

Hello,

On my iPad I currently have my exchange account mapped. When I open the native calendar app and open a meeting that has 20 invitees on it, the only invitee I see is myself. I can open the same meeting in outlook 2010 and all of the invitees show up. I am currently running 8.1.2. My exchange account is hosted on Office 365, and everything has worked fine until about a week ago. Thank you for any help or tips you can provide!
