With Outlook 15, connection is made easier and especially when your personal email accounts support the rich capabilities of Exchange Active Sync including the new @outlook.com email address. Also, there’s no need for you to use Outlook Connector add-in to do this.
Outlook 15 uses the newly-added support for the rich Exchange Active Sync protocol that has become the gold standard used by smartphones and other mobile devices. It will sync mails, calendar, contacts and tasks from the new Outlook.com account.
With Outlook 15, your Hotmail accounts will automatically get migrated to connect via EAS. There is no need to add accounts again and you can access the other email accounts you have set up as well.
