(JavaScript) Outlook -- List Mail Folders

See more Outlook Examples

Uses the Microsoft Graph API to list Outlook mail folders.

Note: This example requires Chilkat v9.5.0.67 or greater.

For more information, see https://docs.microsoft.com/en-us/graph/api/user-list-mailfolders?view=graph-rest-1.0&tabs=http

Note

This example is intended for running within a Chilkat.Js embedded JavaScript engine. All Chilkat JavaScript examples require Chilkat v11.4.0 or greater.

var success = false;

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

var http = new CkHttp();

// 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).

http.AuthToken = "MICROSOFT_GRAPH_ACCESS_TOKEN";

var sbResponse = new CkStringBuilder();

// Sends:  GET /users/{id | userPrincipalName}/mailFolders
// Note: It is also possible to use the literal string "me" for the current logged-on user.
// For example: GET /me/mailFolders
http.ClearUrlVars();
http.SetUrlVar("userPrincipalName","chilkatsoft@outlook.com");
success = http.QuickGetSb("https://graph.microsoft.com/v1.0/users/{$userPrincipalName}/mailFolders",sbResponse);
if ((success !== true) && (http.LastStatus == 0)) {
    console.log(http.LastErrorText);
    return;
}

var json = new CkJsonObject();
json.LoadSb(sbResponse);
json.EmitCompact = false;

console.log("Status code = " + http.LastStatus);
if (http.LastStatus !== 200) {
    console.log(json.Emit());
    console.log("Failed.");
}

console.log(json.Emit());
console.log("----");

// In my test case, this is the result (see below)
// Apparently, this lists folders without listing subfolders (aka child folders)
// There's another REST API call to list child folders.

// To iterate over the folders:
var i = 0;
var numFolders = json.SizeOfArray("value");
while (i < numFolders) {
    json.I = i;
    console.log(json.StringOf("value[i].displayName"));
    i = i+1;
}

// The output from the above loop:

// 	Archive
// 	Deleted Items
// 	Drafts
// 	Inbox
// 	Junk Email
// 	Outbox
// 	Sent Items
