    // See Global Unlock Sample for sample code.

    // Use your previously obtained access token here:
    // See the following examples for getting an access token:
    //    Get Microsoft Graph OAuth2 Access Token (Azure AD v2.0 Endpoint).
    //    Get Microsoft Graph OAuth2 Access Token (Azure AD Endpoint).
    //    Refresh Access Token (Azure AD v2.0 Endpoint).

    // Sends:  GET /users/{user_id | userPrincipalName}/mailFolders/{folder_id}/messages

    // but we must specify the corresponding folder_id.  The best way to do this is to create
    // a local map of folderPaths-to-folderIds.
