Note, I first logged this in the Office forums. It was suggested I re-enter here.
Outlook 2013 notification photos are mismatched!
Environment; Office 2013 on Windows 8, with Office 265 Exchange hosting.
When I get email from a colleague (i.e. someone else on Exchange/ActiveDirectory -- where their photo is stored in AD), I get the notification pop-out with (a) a photo of the sender (if available) and (b) the sender's name.
However, I sometimes find that the photo (if shown/available) doesn't match the sender.
