Server Role Status Panel

This panel shows the Exchange 2007 roles that are installed. This information includes:

 
Table 2. Exchange 2007 server role status panel.
Component
Description

MBX

Shows whether the Mailbox role is installed on this Exchange 2007 server. The Mailbox role is responsible for hosting mailbox and public folder data. It also provides MAPI access for Outlook clients.

UM

Shows whether the Unified Messaging role is installed on this Exchange 2007 server. The Unified Messaging role enables you to access their mailbox, address book, and calendar using telephone and voice. Note that IP-PBX or VoIP gateway must be installed to use the functionality of the Unified Messaging role.

CAS

Shows whether the Client Access role is installed on this Exchange 2007 server. The Client Access role provides mailbox server protocol access apart from MAPI. It allows you access to the mailboxes using Outlook Web Access (OWA), POP3/IMAP4, and ActiveSync.

EDG

Shows whether the Edge Transport role is installed on this Exchange 2007 server. The Edge Transport role provides mail quarantine and SMTP services to enhance security. It is the first hop of incoming mail and the last hop of outgoing mail. Note that it does not require AD access so that it can function with limited access to the corporate network (for added security).

HUB

Shows whether the Hub Transport role is installed on this Exchange 2007 server. The Hub Transport role handles mail flow by routing messages to either another Hub Transport server, an Edge server, or a Mailbox server. This role uses AD site info to determine the mail flow.

Transport-In Panel

The Transport-In panel groups components that represent current inbound connections to this Exchange 2007 server. This information includes:

 
Table 3. Exchange 2007 transport-in panel.
Component
Description

Connections

Shows the total number of inbound SMTP connections established by other SMTP hosts to this Exchange server. The number of connections represents the sum of all SMTP inbound connections from all remote domains to SMTP Receive Connectors on this Exchange 2007 server.

Connectors

Shows the number of SMTP Receive connectors on this Exchange 2007 server that can accept mail from other SMTP servers.

Submission Queue

Shows the number of items in the Submission Queue. The submission queue holds messages before they are consumed by the Categorizer which determines what to do with the messages based on information about the intended recipients.

After the submission queue, the Categorizer then routes the message to either an Edge Server role, another Hub server in a different AD Site, a mailbox on an Exchange server, or the Unreachable Queue.

Transport Panel

The Transport panel groups components that identify the status of the various transport queues on this Exchange 2007 server. This information includes:

 
Table 4. Exchange 2007 transport panel.
Component
Description

Unreachable Queue

Shows the number of messages in the transport unreachable queue on this Exchange 2007 server. The Unreachable Queue contains any messages that cannot be routed to their final destination.

Poison Queue

Shows the number of potentially harmful messages on this Exchange 2007 server. Messages that contain content that might be damaging to the Exchange Server system are by default delivered to this Poison Queue and suspended. If messages in this queue are deemed not harmful, message delivery can be resumed, and the message enters the Submission Queue.

Mailbox Delivery Queue

Represents the number of items in the Transport Mailbox Delivery Queue on this Exchange server. The mailbox delivery queue holds messages that are being delivered to mailbox recipients whose mailbox data is stored on a Mailbox server role located in the same site as this Transport server. The next hop for a message in this queue is the distinguished name of the destination mailbox store.

LDAP Search Time (ms)

Shows LDAP Search Time (in milliseconds) for the transport to send an LDAP search request to Active Directory, and receive a response on this Exchange 2007 server. Exchange 2007 uses Active Directory (AD) as a repository for mailbox and mail routing configuration data. Exchange 2007 servers issue LDAP queries against Active Directory to retrieve message routing data.

Transport-Out Panel

The Transport-Out panel groups components that represent current outbound activity from the Exchange 2007 server. This information includes:

 
Table 5. Exchange 2007 transport-out panel.
Component
Description

Connections

Shows the current number of outbound SMTP connections to other SMTP hosts. The number of connections represents the sum of all SMTP outbound connections from SMTP Send Connectors on this Exchange 2007 server to all remote SMTP domains.

Connectors

Shows the number of SMTP Send connectors on this Exchange 2007 server that can service connections to other SMTP servers.

Remote Delivery Queue

Shows the number of messages in the transport that are queued for delivery to a remote server using SMTP. The Exchange 2007 Hub and Edge roles can have multiple remote delivery queues. Each queue contains messages with recipients that share the same remote server destination. On a Hub role server, the destination servers are within the same Exchange Organization as this Exchange server, but in a different AD Site. For the Edge role, the destination servers are external to the Organization, and handle message delivery for external SMTP domains.
