Outlook on my iPhone keeps showing an unread message when there isn't one

So, in the last week or so my inbox for my microsoft exchange account on my iPhone constantly shows 1 unread message. There is no unread message and when I go to find the unread messages, its not there. I have tried marking all as unread and then read, I have reset the program, I have reset my phone and nothing has worked. Also, its strange that while it shows an unread message when I am in the microsoft exchange account on my phone, it does not show up as a read bubble over my email app.

Has anyone seen this? Is there some way to fix it? I'm not generally OCD, but its driving me mad. Help me reddit...you're my only hope.
