We have an Exchange 2013 DAG and we recently started not allowing users to change their own photos. All user photos have been uploaded into AD using the thumbnailPhoto attribute. The trouble is, previous to this, some people deleted their photos and some changed them to something other than their face.
Right now we're in a situation where the right photo is stored in AD but users who've changed or deleted their photos in the past aren't showing. All other users' photos are showing fine. I'm looking for a way to have Exchange show the latest photos from AD for the users who've modified them in the past.
