How to Setup Hotmail on iDevice

Microsoft today rolled out Exchange ActiveSync (EAS), which lets users get push notifications on phones and other mobile devices, as part of the Wave 4 release of Windows Live Hotmail. Some users reported EAS working for them two months ago, but only now has Microsoft made it official: e-mail, calendar, and contacts can be pushed automatically to your phone from Hotmail. To enable EAS, use the following settings:

Field	Setting
Server/URL	m.hotmail.com
Username	Full e-mail address (such as: yourname@hotmail.com)
Domain	Leave this blank
SSL	Enable this
Certificate	Accept the SSL certificate when prompted
Mail, Contacts, Calendar, Tasks	All can be enabled

Many phones already support ActiveSync for connecting to an Exchange server, but the feature will be particularly useful on phones that support dual ActiveSync accounts, including devices running Microsoft's upcoming Windows Phone 7 OS. Users who don't connect to an Exchange Server, but still have a device with ActiveSync support can also use the new Hotmail feature. Microsoft says over 300 million mobile devices currently support EAS; a full list is available on the Windows Live Solution Center.

Hotmail users have been begging for IMAP and other enhanced syncing capabilities for ages. Microsoft still won't budge on IMAP, but the company did rollout POP3 last year, and now with EAS support this year, it's clear the software giant is finally listening.
