Exchange services

You can monitor the following critical Exchange services to determine whether the service is available (Up) or is disabled (Down).

Select this process:

If you want to:

Information Store

Monitor the MAPI message store service. The information store can contain messages, forms, documents, and other information created by users and applications. It provides each user with a server-based mailbox and stores public folder contents.

Site Replication Service

Monitor the Site Replication service.


Monitor the Management service.

MTA Stacks

Monitor the Mail Transport Agent (MTA) service. The MTA service provides the engine for sending messages and distributing information between Microsoft Exchange Server systems or between Microsoft Exchange Server and a foreign system. Each MTA is associated with one information store. It is accessed using MAPI calls only and has no direct programmer interface with Microsoft Exchange Server. The MTA conforms to the 1988 X.400 specification.

System Attendant

Monitor the System Attendant service.

Routing Engine

Monitor the Routing Engine, which determines the routes for delivering messages to remote addresses. It forwards the message to remote Exchange addresses using SMTP. If some addresses are on a foreign messaging system, the routing engine assigns the message to a gateway that handles the address type of the recipient and passes the message to the message transfer agent (MTA).


Monitor the Event service, which reports warnings and errors.


Monitor the POP3 service, which lets a mail client access mail on the server.


Monitor the IMAP4 service, which lets a mail client access mail on the server.
