Microsoft announce that there will be some changes to the licensing and activation of the subscription-based Office clients such as Office 365 ProPlus.
Users will be able to install Office on a new device without being prompted to deactivate Office on another device when they reach the five-device limit, and will simply be signed out of Office on the device where Office has been least recently used.
These changes will start rolling out to customers from August, with exact timings dependent on which release channel a customer is using.
