Microsoft recently announced that Office 365 apps will no longer run on macOS 10.13 High Sierra as of November 10, as the company shifts focus to newer operating systems.

Updating macOS, the best way to go
Needless to say, if you continue to run the Microsoft Office app on macOS 10.13 or later, everything will work as before, only no other enhancements will be released.
