It may be the only way for people to actually see who they are talking with. This is why companies want to display users’ photographs in Office 365 applications like SharePoint Online, OWA, Outlook, or Skype for Business. In most cases, if you need to upload photos of just a few users to Office 365, it isn’t a big deal.
