We’ve known Windows Live Hotmail was due to receive an Exchange ActiveSync (EAS) update for months.
Today, it’s arrived.
The new Exchange service supports Windows Mobile 6, Windows Phone 7, and the Apple iPhone. Android support is not yet official, but it may work with your Android-powered device, so give it a try (Android 2.1 is not supported yet; Microsoft will release a list of tested Android phones soon).
Here are the general settings for configuring your device for Exchange ActiveSync Windows Live Hotmail:
Server / URL: m.hotmail.com
Username: Full email address, for example: someone@example.com
Domain: Leave this blank
SSL: Enable this
Certificate:Accept the SSL certificate when prompted
You can find a detailed set of configuration settings instructions for devices here.
