We know you’ve been waiting to see the new Exchange Web Services features in Exchange 2010 SP1 exposed in the EWS Managed API, and I’m here to tell you that your wait is over. The Exchange Web Services Managed API 1.1 is now available for download. The EWS Managed API 1.1 exposes the following features that were introduced in Exchange 2010 SP1:

· Archive mailbox – Access to archive folders and items. Everything you can do with mailbox items and folders is available for your archived information. Equal access for all items and folders!

· Conversations – Emails are social and so is your application, so try the new Conversations feature exposed by EWS to easily manage email conversations.

· Inbox Rules – Would you like to tell your Exchange server where to store it (emails)? Server-side Inbox rules are now available as a programmatic interface for your Exchange client applications. For more information, see Working with Inbox Rules.

· Streaming Notifications – Want your cake and eat it too? Now you can with streaming notifications. Streaming notifications provide you with the benefits of both push and pull event notification models.

For a convenient chart that lists applicable features by server and API versions, see Introduction to the EWS Managed API.

And before I forget, make sure you visit the important companion to the EWS Managed API 1.1, the Exchange Web Services Managed API 1.1 SDK.

It’s time to rev your application!
