Managing personal Outlook.com account settings, security, and privacy
Hi & welcome too,
In order to release member information in a civil matter regarding an MSN or Windows Live account, Microsoft must first receive a validly served subpoena or court order.
Please address the appropriate legal document to Microsoft Corporation and include all pertinent information for Microsoft to identify the particular MSN or Windows Live account(s) you seek to locate.
Microsoft will respond to formally served civil subpoenas served on Microsoft’s registered agent in the requesting party’s state and is unable to respond to faxed or mailed requests for civil matters.
Please call the Microsoft Online Services Legal Request Hotline at (425) 722-1299. The hotline is available to help with these issues.
