Hotmail Refresh Access Token (also for Live.com, Outlook.com)

See more OAuth2 Examples

An 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.

//  This example requires the Chilkat API to have been previously unlocked.
//  See Global Unlock Sample for sample code.

//  It is assumed we previously obtained an OAuth2 access token.

//  Note: Refreshing an access token does not require user-interaction.  
//  Only the act of getting the initial access token requires interactive authorization from the Hotmail account owner 
//  (i.e. a browser is displayed and the Hotmail account owner authorizes access by the app).

//  Once you have the initial access token, it can be refreshed for a long time.
//  A typical strategy is to write your application to automatically refresh the access token 
//  when authentication fails, and then retry the operation with the new access token.
