In my previous article, I discuss best practices on how to choose high resolution photos to use in user profile pictures for Office 365.
You can upload user profile pictures using the Office 365 Admin Center. It may be obvious to everyone else, but I didn’t know this was possible until a very astute coop student showed me this feature (after I spent an afternoon telling him the only way to do this was to use PowerShell). So, to save you the embarrassment, here is the web-based method:
Repeat for all user profiles pictures you wish to upload. If you have Lync open, you should see the results almost immediately.
The profile picture will also be automatically synched with SharePoint user profiles (at least, that has been my experience… please feel free to comment below if you’ve had different results).
While it may be handy to do a few pictures, if you have to update hundreds of user profile pictures, you may want to use the PowerShell method.
