Microsoft has revealed that the next version of its standalone productivity software suite will be called Office 2019, and is expected to release next year. “Perpetual” is what Microsoft calls its standalone software package where Office can be installed on a single computer only, and for which the customer pays a license fee once only.

Microsoft has introduced some fish-hooks for the perpetual version of Office, however.
In April this year, Microsoft said that starting October 2020, users with perpetual versions of Office will be required to connect to Office 365 services.
Only users with the latest supported version of Office perpetual will be able to connect to Office 365 services, meaning those with older variants of the productivity suite will have to upgrade their software.
Office 2019 will come with new Exchange, SharePoint and Skype for Business services, which Microsoft said will have better manageability, usability, security and updated voice capabilities.
