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

Chilkat.Http http = new Chilkat.Http();

// 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).
//    Refresh Access Token (Azure AD Endpoint).

Chilkat.StringBuilder sbResponse = new Chilkat.StringBuilder();

// Sends:  GET /users/{user_id | userPrincipalName}/mailFolders/{folder_id}/messages
// Note: It is also possible to use the literal string "me" for the current logged-on user.
// For example: GET /me/mailFolders/{folder_id}/messages

http.SetUrlVar("userPrincipalName","chilkatsoft@outlook.com");

// In this example, we'd like to get the messages in the folder "/Inbox/abc",
// but we must specify the corresponding folder_id.  The best way to do this is to create
// a local map of folderPaths-to-folderIds.
// This example does it:  Create Outlook Folder Map)
