Hi BillJenn,
If you're installing Microsoft 365 on other computers in your office and want to avoid syncing personal documents. Try the following below.
Install Microsoft 365 Apps using your organization’s subscription but avoid signing in with personal Microsoft accounts.
Skip OneDrive setup during installation or unlink it afterward to prevent automatic syncing.
In each Office app (Word, Excel, etc.), go to File > Options > Save and disable AutoSave to OneDrive.
Save files locally or to a shared network location instead of cloud storage.
If possible, use separate user profiles on each computer to keep workspaces and documents isolated.
This way, each computer can use Office apps without accessing or syncing documents opened by you or others.
Let me know if you have any questions.
