When customers connect to Office 365 with a legacy version of Office, they’re not enjoying all that the service has to offer. The IT benefits—particularly security—are cut short. And the end user experience in the apps is limited to the features shipped at a point in time. To ensure that customers are getting the most out of their Office 365 subscription, we are updating our system requirements.
- Office 365 ProPlus or Office perpetual in mainstream support required to connect to Office 365 services. Starting October 13, 2020, Office 365 ProPlus or Office perpetual in mainstream support will be required to connect to Office 365 services. Office 365 ProPlus will deliver the best experience, but for customers who aren’t ready to move to the cloud by 2020, we will also support connections from Office perpetual in mainstream support.
- Applies to Office 365 commercial services only. This update does not change our system requirements or support policies for the Office perpetual clients, Office perpetual clients connecting to on-premises servers, or any consumer services.
- More than three years’ notice. We’re providing more than three years’ notice to give IT time to plan and budget for this change. Until this new requirement goes into effect in 2020, Office 2010, Office 2013 and Office 2016 perpetual clients will still be able to connect to Office 365 services.
Targeting September 2017, we will make the following changes to the Office 365 ProPlus update model:
- Two updates a year. We will reduce the Office 365 ProPlus update cadence from three to two times a year, with semi-annual feature updates to Windows 10 and Office 365 ProPlus targeted for March and September.
- 18 months of support. We will extend the support period for Office 365 ProPlus semi-annual updates from 12 to 18 months (starting from first release) so IT professionals can choose to update once or twice a year.
- System Center Configuration Manager support. System Center Configuration Manager will support this new aligned update model for Office 365 ProPlus and Windows 10, making it easier to deploy and update the two products together.
