Hotmail has announced the support of Push notifications for it’s Mail, Calendar and Contacts for the iPhone, iPod touch and iPad with the support of Exchange ActiveSync. With the support of Exchange ActiveSync, you can now keep your emails, contacts and calendar items updates which means anytime you check, delete or send out a new email, it will be synced with the web version of hotmail in no time. Previously, you had to access the web version of hotmail and syncing it just like you do with your Gmail on iPhone/iPad was not possible.

Here’s what the official announcement says:

Hotmail is making it easier for you to stay up-to-date and be productive on your phone. Starting today, you can get your email, calendar, and contacts pushed automatically to your phone using Exchange ActiveSync (EAS). EAS keeps everything in sync between your phone and Hotmail, so whatever you do on your phone, like delete an email, add an appointment, or update one of your contacts with a new number, will also be reflected on the web, and vice-versa. If you use an email client on your PC that already syncs with Hotmail, like Outlook with the Outlook Connector or Windows Live Mail, what you do on your phone will show up there as well, delivering a seamless experience for managing your stuff between your PC email client, your browser, and your phone.

How to Setup ActiveSync for iPhone, iPod Touch and iPad:

    URL - m.hotmail.com 
    Username - Enter full name with domain info, e.g. john@hotmail.com
    Domain - Leave blank 
    SSL - Enabled 
    Certificate - Accept the SSL certificate when prompted
    Mail, Contacts, Calendar, Tasks - All can be enabled.

Note: If you already have an ActiveSync profile then you will have to delete it first before applying these settings. (via WindowsTeamBlog)
