A family of Microsoft word processing software products for creating web, email, and print documents.
Automatic saving only works in connection with OneDrive.
When saving locally, you can use "Save AutoRecover information every X minutes" (at File > Options > Save) but this is designed to provide basic backup when Word has crashed. This feature does not replace manual saving.
Note that decision makers and developers at Microsoft do not read the Q&A forums. To suggest product improvement, you need to post in the feedback portal at https://feedbackportal.microsoft.com/feedback/forum/fb6d67e3-301c-ec11-b6e7-0022481f8472 .
