When control+clicking to pull up the contextual menu and selecting 'View Source' for any email, a pop-up window appears with the following message:

"The document “Outlook_MessageSource_2014-12-07 08/47/54 +0000_0” could not be opened. You don’t have permission. To view or change permissions, select the item in the Finder and choose File > Get Info."

Yet when i search for the file listed in this message nothing shows up, and i include system files in my search. I also checked some email message files ending in "olk14message" and they open fine in Outlook, so I'm very confused by this. I also repaired permissions but no change. This is the first time I've ever had this happen and I have used the 'View Source' feature countless times.
