title: Using Oauth2 to send email via Office365 C#
body: <p>I'm trying to send email in c# using Oauth2 with an office 365 account.</p>
  <p>Currently I am able to get the token but not sure how I'm able to use that token and send the email.</p>
  <p>System.Net.Mail does not support OAuth or OAuth2.</p>
  <p>I've seen Mailkit but the samples are all for google mail and didn't see one for office 365 so I'm not really sure where to start.</p>
