Here is another issue I have come across whereby an AD user Photo is visible in Outlook 2010 but not their Lync Client. The program I have been using to upload the photos is a free download from Exclaimer and Link is given below.
So, the start of my issue is as followed; The user below Naim has a picture uploaded via Exclaimer Outlook Photos but the image is not showing in the Lync Client.
I have had to make a change to the CsClientPolicy for MaxPhotoSizeKB. The statement from Technet about this command is as followed
Indicates the maximum size (in kilobytes) for photos displayed in Lync 2010. Setting the MaxPhotoSize to 0 prevents any photos from being displayed in Lync 2010.
