Hi All,
We are in the final stages of our preparation to roll out Windows 8.1 using SCCM2012....and we'd like to use the thumbnailPhoto attribute already populated for our user base in the Windows 8.1 tile. We already have Outlook and Lync pulling this attribute out and diplaying fine, so it's just a solution for the 8.1 tile that is missing.
Having tried many blogs and other links, nothing seems to work.
