(Unicode C) Hotmail Refresh Access Token (also for Live.com, Outlook.com)See more OAuth2 ExamplesAn OAuth2 access token is typically valid for 1 hour. Interaction with the Hotmail account owner via a browser is only needed for getting the initial access token. Once you have it, it can be continually refreshed without user interaction for a long time. See: How Long can an OAuth2 Access Token be Refreshed?
