Microsoft OneDrive

No product-specific finding beyond Microsoft's overall framework. The item worth recording is that OneDrive is configured on many Windows installations to back up Desktop, Documents and Pictures by default, so a large number of users are syncing their entire working life to a cloud service they did not deliberately choose to use. Combined with Copilot's permission-inheritance behaviour documented in the LLM Providers tab, the practical result is that files land in a searchable cloud index through a default rather than a decision.

Arbitration

Same as Microsoft overall.

Data sharing

No product-specific lawsuit independently confirmed this pass beyond Microsoft's overall corporate findings (see Microsoft/Outlook row, Consumer Apps tab, for the Russo v. Microsoft business-customer data-sharing lawsuit).

Contacts

Privacy contact. No published privacy email; Microsoft routes requests via microsoft.com/concern/privacy (30-day response commitment)

Legal notice. PUBLIC COMPANY (MSFT). Service route: c/o General Counsel / Corporate Secretary, Redmond, Washington — the corporate address on the SEC Form 10-K cover page is the official address of record. Confirm the exact street address on the current 10-K at sec.gov/edgar, and check the state-of-incorporation registered agent (usually Delaware; most large filers use The Corporation Trust Company or Corporation Service Company) via the Secretary of State business-entity search. A registered agent MUST accept service, which is why it is the reliable channel when a company publishes no privacy address.
