Office insists to save to one drive.

[Pablo2000]

I don't use and never will use one drive. How do FORCE MS to accept this?

[Stefan Blom]

In Word, click File > Options > Save. Select the option to "Save to Computer by default" and specify a "Default local file location."

Note that any existing documents that have been saved online, or synchronized with OneDrive, must be moved out of the local folder which is being synchronized with OneDrive.

To prevent OneDrive from synchronizing any of your local files, unlink OneDrive. See How to cancel or stop sync in OneDrive - Microsoft Support. In particular, see the section "Stop syncing everything" (screen shot below).

Stefan has told you how to stop Word defaulting to OneDrive or accessing OneDrive. Unfortunately, Microsoft's business model is centered around use of it. You can expect that at some time in the future you will have to turn it off again.
