local chilkat = require("chilkat")

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

local mailman = chilkat.MailMan.new()

mailman.mail_host = "outlook.office365.com"
mailman.mail_port = 995
mailman.pop_ssl = true

-- Use your O365 email address here.
mailman.pop_username = "OFFICE365_EMAIL_ADDRESS"

-- When using OAuth2 authentication, leave the password empty.
mailman.pop_password = ""

-- Load our previously obtained OAuth2 access token.
local jsonToken = chilkat.JsonObject.new()
local success = jsonToken:load_file("qa_data/tokens/office365.json")
if not success then
    print(jsonToken.last_error_text)
    return
end

mailman.oauth2_access_token = jsonToken:string_of("access_token")

-- Make the TLS connection to the outlook.office365.com POP3 server.
success = mailman:pop3_connect()
if not success then
    print(mailman.last_error_text)
    return
end

-- Authenticate using XOAUTH2
success = mailman:pop3_authenticate()
if not success then
