On February 8, 2007, Rebecca and I hosted a TechReady 4 breakout session titled Exchange Web Services: Developing for Exchange Server 2007. The purpose of this session was to show how easy it is to integrate Microsoft Exchange Server 2007 data within line-of-business applications and third-party solutions by using the new Exchange Web Services feature.

This article provides an overview of the samples that we demonstrated in the breakout session. To download the slides and sample code, see TechReady 2007 Exchange Web Services Samples.

The samples that are provided with this article are for information only and are not for use in a production environment. These samples are not supported.

The TechReady 2007 Exchange Web Services Samples download includes the following projects:

  • CreateMeetingAndSendInvitationsDemo
  • AutodiscoveryDemo
  • PullNotificationsDemo
  • AvailabilityDemo

The download also includes a supporting project named EWSProxies, which creates an assembly called EWSProxies.dll that provides access to parts of Exchange Web Services that the samples require. Each sample references the EWSProxies project and uses the methods and properties in that project to access Exchange Web Services.

The CreateMeetingAndSendInvitationsDemo sample uses Exchange Web Services to create a meeting in one user's calendar and then invite another user to the meeting. This sample demonstrates how Exchange Web Services helps simplify previously lengthy implementations of common operations. The WebDAV sample that performs the same function has many more lines of code than the CreateMeetingAndSendInvitationsDemo sample.

The AutodiscoveryDemo sample uses the specified autodiscovery URL to look up the Exchange Web Services binding information for the specified user. The form in the sample displays the XML of the autodiscovery response as text.

The PullNotificationsDemo sample creates a pull notification subscription on a user's mailbox. When you click the button on the form, the sample sends a message to that user from a second user. The sample periodically retrieves a list of new events that are associated with the subscription to determine whether there are any new messages in the first user's mailbox. It then displays the results in a text box.

The AvailabilityDemo sample gets availability information for two specified users and displays that information in a text box. The sample also enables you to get Out of Office (OOF) settings information about the first user by selecting the OOF Settings tab and clicking the button on the form.

Before you run any of the samples, you must change the code to reflect your specific environment. The following table lists the changes that you must make to the code for each sample.
