Transport-In Panel

The Transport-In panel groups components that represent current inbound connections to this Exchange 2010 server. This information includes:

 
Table 3. Exchange 2010 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 2010 server.

Connectors

Shows the number of SMTP Receive connectors on this Exchange 2010 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 2010 server. This information includes:

 
Table 4. Exchange 2010 transport panel.
Component
Description

Unreachable Queue

Shows the number of messages in the transport unreachable queue on this Exchange 2010 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 2010 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 2010 server. Exchange 2010 uses Active Directory (AD) as a repository for mailbox and mail routing configuration data. Exchange 2010 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 2010 server. This information includes:

 
Table 5. Exchange 2010 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 2010 server to all remote SMTP domains.

Connectors

Shows the number of SMTP Send connectors on this Exchange 2010 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 2010 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.

Clientsl Pane

The Clients panel groups components that represent current client connections and associated latency to this Exchange 2010 server. This information includes:

 
Table 6. Exchange 2010 clients panel.
Component
Description

MAPI

Indicates the number of MAPI user connections to this Exchange 2010 server. The Mailbox role provides MAPI access for Microsoft Outlook clients, and enables these types of connections.

OWA

Indicates the number of current unique OWA users logged on to this Exchange 2010 server. The Client Access role provides OWA to allow you to access his or her mailbox from a web browser and have full access to all the information in the mailbox including task lists, calendar information, mail items, public folders, UNC shares (\\servername\share) and SharePoint documents. This value is decremented when a you log off your OWA session or the session times out.

ActiveSync

Shows the number of current secure HTTP connections (HTTPS) that are established from Windows Mobile-based or Exchange ActiveSync-enabled mobile devices and this Exchange server. ActiveSync is a push orientated protocol. Data such as user messages, schedules, contact information and tasks are synchronized over the HTTPS connection.

Outlook Anywhere

Shows the number of unique users currently connected to this Exchange 2010 server via RPC/HTTP. The Outlook Anywhere feature, formerly known as RPC over HTTP, lets clients that use Microsoft Office Outlook to connect to their Exchange servers from outside the corporate network or over the Internet using the RPC over HTTP Windows networking component.

POP3

Shows the number of POP3 connections to this Exchange 2010 server. The Client Access role provides POP3 access to mailbox data for clients that rely on this protocol.

IMAP4

Shows the number of IMAP4 connections to this Exchange 2010 server. The Client Access role provides IMAP4 access to mailbox data for clients that rely on this protocol.

Latency (ms) (for MAPI)

Shows the average latency for MAPI clients connected with Outlook to this Exchange 2010 server providing the Mailbox role.

Latency (ms) (for OWA)

Shows the average latency for OWA clients on the Exchange 2010 server.

Latency (ms) (for ActiveSync)

Shows the average latency for ActiveSync clients on the Exchange 2010 server.

Latency (ms) (for POP3)

Shows the average latency for POP3 clients on the Exchange 2010 server.

Latency (ms) (for IMAP4)

Shows the average latency for IMAP4 clients on the Exchange 2010 server.
