Microsoft, as promised, began rolling out ActiveSync support for Hotmail on August 30.

Hotmail ActiveSync enables users to get their mail, calendar and contacts pushed automatically to their phones using the Exchange ActiveSync protocol. Changes made on phones will be reflected on the Web and vice-versa. For users already using e-mail clients on their PCs that currently sync with Hotmail -- like Outlook with the Outlook Connector or Windows Live Mail -- Hotmail sync also will be supported.
LiveSide.net noted back in June 2010 that Microsoft was testing ActiveSync for Hotmail, and that a number of users had it working. In mid-August — shortly after Microsoft announced it had completed rolling out the new Hotmail Wave 4 release to all of its Hotmail users — LiveSide reported that some users were able to access ActiveSync for Hotmail, but some were not
