# Exchange Web Service Connector

The Exchange Web Service Connector retrieves messages, appointments, contacts, and other items from Microsoft Exchange. The Exchange Web Service Connector uses the Exchange Web Service to retrieve data, and can also use the Microsoft Graph API to enable some optional features.

The connector first obtains a list of mailboxes that it can synchronize. If you are connecting to an Exchange Server, the connector can retrieve a list of mailboxes through LDAP. If you are connecting to Exchange Online, you can either provide a list of mailboxes to synchronize, or configure the connector to obtain a list through the Microsoft Graph API.

After it has a list of mailboxes to synchronize, the connector retrieves all the items from each mailbox, and all the items in public folders. You can configure the connector to retrieve items from specific mailboxes or folders. Messages are retrieved through the Exchange Web Service.

The connector authenticates with the Exchange Web Service using OAuth authentication (basic authentication is also supported for on-premise Exchange servers). The Microsoft Graph API requires OAuth authentication. Authentication for each API is configured separately.

The connector can:

- Keep your text index up-to-date with the information in the Exchange repository.
- Collect documents from the Exchange repository and send them, with metadata, to a specified location such as a shared folder on disk.
- Insert e-mail message (`.eml`) files into the Exchange repository.
- Delete messages from the Exchange repository.
- Retrieve a document from the repository in its original format.
