The Outlook.com team has announced during a Reddit AMA that the email service now supports IMAP and OAuth 2.0. The announced IMAP support was added to increase the potential reach of Outlook, and the addition of OAuth gives developers the ability to build on top of the service, according to a post on the Outlook blog:
In addition to offering more complete device connectivity, IMAP (along with OAuth) gives developers opportunities to build third-party clients and services that offer value-added scenarios on top of your Outlook.com email. We are excited to launch the first set of services today that integrate with Outlook.com, and look forward to sharing many more in the future.
Outlook.com has long supported Microsoft's own Exchange Active Sync, but that prevented it from being used by many email apps, including Mail on the Mac. Microsoft has announced that TripIt, Sift, Slice, motley*bunch, Unroll.me, OtherInbox, and Context.IO are the first services and applications to take advantage of the IMAP implementation. More services are sure to take advantage of this new support soon.
