Some of these technologies enable your applications to work with data that is stored in Exchange, and others are used to manage and control the Exchange server. In many cases, you can use more than one programming technology or language to accomplish a task, which makes it possible for you to use the technologies and languages that you are familiar with. For example, you can set properties on items in the Exchange store by using the Mail REST API, EWS, or the EWS Managed API.

Exchange interacts with custom applications in a variety of ways, depending on the application architecture and functionality. At its core, Exchange not only transports messages, but also maintains mailboxes, executes form-based applications, and more.

Exchange interaction

Description

Message transport

Exchange serves as a standard mail server for applications that send messages. Exchange includes several APIs that transfer messages, including REST, EWS, and the EWS Managed API. In addition, applications can use transport agents to respond as messages are processed and delivered by Exchange.

Mailbox storage

Exchange provides a hierarchical structure of folders, items, and properties for applications that access data stored in mailboxes. You can access that stored information by using a combination of database and component object styles. You can perform queries on the data, and Exchange manages access to the stored data based on user and store permissions. Applications that handle mailbox data typically use REST, EWS, or the EWS Managed API.

Managed enterprise server

Exchange functions as a managed server for applications that manage Exchange servers and stores. Applications can configure, control, and monitor current activity and the health of Exchange servers across the organization. Exchange management applications use the Exchange Management Shell to manage Exchange servers.
