I have just bought my first Mac and struggling to work out how I change the colour of unread emails on Office for Mac?  It's very simple on windows, but doesnt seem to be an obvious solution on the mac version?
My inbox (Outlook 2011 for Mac) is displaying 3 unread messages, but they do not appear to actually exist. I have cleared all Filters from my inbox, to no avail. I have also done an Advanced Search for emails with an Unread Status, but the emails do not appear in the search results there either. I have checked all sub-folders of my Inbox, and the messages are not there either.

Any idea what might be going on? I am using an Exchange server, and I have seen other users talk about possible sync issues in certain Exchange scenarios, but I have no idea if that might be my problem.

Thanks!
