Outlook web users will soon get a few extra features and improvements if they have an Office 365 subscription commercial subscription.

These additions will be rolled out to all Office 365 commercial users by the end of March 2016. The new address book features will also be added to the PC, iOS and Android Outlook clients in the first half of 2016.
