Do not cache photos in Skype for Business
When attempting to remove photos for all users in my organization, the photos seem to be cached in Skype for Business, with no way to remove them as a systems admin.
Active Directory, Exchange, Exchange Onlie, and Skype for Business all reported that no users had a photo, yet the photo was present ONLY when Skype was open.
This issue was forced to be resolved by Microsoft, and could not be resolved by the Organization having the issue.
Please integrate Skype for Business with Exchange/EO better to allow for complete administration, including removing pictures.
