Office365 Imap not working programatically

Trying to connect to imap using MailKit library. While this code works for Gmail and hot mail. It gives Login Failed error for Office 365.

using (var client = new ImapClient(new ProtocolLogger("imap.log")))
{
      client.Timeout = 120000;
      client.Connect("outlook.office365.com", 
                      93,SecureSocketOptions.SslOnConnect);
      client.Authenticate("[email protected]", "XXXXXPassword");
      client.Inbox.Open(FolderAccess.ReadOnly);

      var uids = client.Inbox.Search(SearchQuery.All);

      foreach (var uid in uids)
      {
         var message = client.Inbox.GetMessage(uid);
         // write the message to a file
         message.WriteTo(string.Format("{0}.eml", uid));
     }
     client.Disconnect(true);
}
