Hello!
We are on an hybrid deployment with some users on Exchange 2013 on-premises and others on Exchange Online (Office 365 E3 plan). We have enabled photo sync (PhotosEnabled attribute) in the organization relationship, both on-premises and online, but while Exchange Online users can see all profile pictures, Exchange on-premises can see only on-premises pictures.
It also looks like that online users can see only a low resolution version of on-premises users' pictures.
Do you have any idea how to troubleshoot or fix this, please?
Thanks!
