Jerry,
Given that, how would I be able to upload user photos into Exchange 2013 Online (and Lync 2013 Online) as an O365 administrator, through the portal UI? I have been going through the site and I don't see a way for me to be able to administratively change user profile photos through the web UI?
Also, am I correct in my understanding that if I upload a user's profile photo through Office 365, that it will automatically create the appropriate size of the user's on-premise Active Directory photo?
