The usage rights for customers to use Office Online Server are extended: the August 2016 Product Terms document states that as long as customers purchase Office Standard 2016 or Office Professional Plus 2016 licences before 1 August 2016 then they may use Office Online Server until 1 August 2019 (page 23). Previously, it was stated that the licences needed to be purchased between 1 May 2016 and 1 August 2016.
