Exchange Collector is a Presence Server component which provides integration with an Microsoft (MS) Exchange Enterprise deployment. Exchange Collector collects and publishes the Calendar and Out of Office Assistant information for Exchange Mailboxes. The Exchange Mailbox servers manage Exchange Mailboxes.

The Exchange server provides an availability service, which makes the availability information of the users available to the external clients. Exchange Collector functions as one of these clients. Exchange Collector uses a polling mechanism to collect Calendar and Out of Office Assistant records from the Exchange server by using MS Exchange Web Service (EWS) and converts these records into presence events. Exchange Collector only collects for Aura users that are configured with a Microsoft Exchange communication address in their communication profile.

Presence Services supports the following versions of MS Exchange Server:

Exchange Collector connects to the Microsoft Exchange server securely using TLS. This connection requires that a Microsoft Exchange server certificate be installed into the Avaya Breeze® platform cluster where Exchange Collector is enabled. Typically, the CA certificate should be installed, as the CA certificate is used to sign the certificates for all the Microsoft Exchange servers in the network if there is more than one. Otherwise, a certificate for each Microsoft Exchange server must be imported into the cluster.
