Office 365 ProPlus Servicing Update

Support for the Oct. 2015 version of Office 365 ProPlus ends in Oct. 2016. The accompanying chart shows selected versions of Office Professional Plus and Office 365 ProPlus and how long Microsoft will support them with Office 365 hosted services.

Office Professional Plus (top of the chart) is licensed per device and is the most common Office suite purchased in Enterprise Agreements. Customers running it continue to have Mainstream and Extended support periods that were offered with earlier versions of Office, and organizations can defer feature updates for the supported life cycle of a version. However, Microsoft will not support Office Professional Plus versions in Extended support with related Office 365-hosted services such as Exchange Online. That means it will not support Office Professional Plus 2013 with Office 365 hosted services after Apr. 10, 2018.

Office 365 ProPlus is licensed on a Per-User basis, and it is the most common suite for large organizations buying Office in Office 365 subscription plans. ProPlus shares code with Office 365 Professional Plus. However, ProPlus versions that have new features appear more frequently, and Microsoft supports each version of ProPlus for a shorter period than it does Office Professional Plus versions.
