Microsoft undoubtedly are keen to no longer have to continue to support interoperability between Cloud Services and On-premise Office Applications. (Office 2019 is not available as MSI install altogether). However, with the December 2018 Product Terms, for a second time, Microsoft have pushed out the date by when local copies of Office Professional are no longer allowed to August 2019. It was supposed to go into effect August 2018 and later January 2019. This seems to recognize the fact that most clients are not fully ready for Click to Run (C2R). In September Microsoft announced to continue to support Office 2016 connections with the Office 365 services through October 2023, a 3 year extension to the previous deadline of October 2020 – this links in with this announcement
What does the updated clause mean?
Under a contract starting (new or renewing) after August 2019 Office Professional can only be installed using the C2R Version (Office 365 Pro Plus) and not the traditional MSI Version.
Who does it affect?
Most Cloud Clients would have transitioned to SPE /M365 E3/E5 From SA already having perpetual rights to Office 2016. These perpetual rights will entitle the Clients to deploy MSI for 2016 and prior versions in perpetuity. Most From-SA Users will not be affected. However, this only applies for users that are licensed with the “From SA” SKU- users added to the same enrolment under a full SKU or Users having “From SA” coming from an Enterprise Subscription Enrollment do not have perpetual rights and will lose the MSI Install rights in any contract starting post August 2019.
