We are unable to update one of our users Skype Pictures. Her picture was older and she requested that we update it with a new one he supplied us with which we uploaded via exchange management console shell. We upload it just how we have uploaded it before which gave no errors. After around 24 hours I checked my Skype for Business to make sure the picture updated and it did. A few days later she contacted us again mentioning the picture did not update. It was still changed on our end but she was still seeing the same picture. This has happened a few times with users and typically we just need to close out of Skype and it updates. When we did this the picture changed to a blank on her end until her next login. We have tried re uploading the picture and going through some of the previous steps again and it still did not update. I Imagine the old picture is save somewhere in a cache on her profile, but I am unable to find where it may be. Does anyone have anything I should try or look for?
