How to enable Auto save for Word Documents in SharePoint On premise

Question

We are trying to edit a document stored in SharePoint server 2019 and we are having trouble with the autosave functionality in the Office clients. The autosave "switch" in the upper left corner of the client is turned off and can't be turned on. If we try to turn it on it just gives an error saying "We couldn't save your file to this location automatically. To avoid losing your changes, please save the file using File > Save.

Please let us know how to enable autosave in SharePoint On Premise.

Please Note: It is SharePoint on premise environment.

Answer 1

What is the version of your office client application?

AutoSave is a new feature available in Excel, Word, and PowerPoint for Microsoft 365 subscribers that saves your file automatically, every few seconds, as you work. 

AutoSave is enabled when working on a file that is saved to OneDrive, OneDrive for Business, or SharePoint Online. If the file is saved to another location (or if it hasn't been saved at all, yet), then AutoSave is disabled. This will happen if your file is on a SharePoint on premises site, a file server, some other cloud storage service, or saved to a local path like C.
