Exchange Internal Server Delivery Health Test

The Exchange Internal Server Delivery Health test is used to monitor the sending and receipt of messages within an Exchange organization.This test sends a test message from each target server in the test to every other target server.

The Exchange Internal Server Delivery Health test sends a test message from each selected server to every other selected server. For example, if you select your whole organization as the test target and your organization has five mailbox servers, this test sends 20 test messages (5 source servers x 4 destination servers) at each monitoring interval.

This health test is not supported for Exchange 2013 and later. This test is also not useful for Exchange 2010 organizations that have implemented Database Availability Groups (DAGs) since mailboxes in a DAG are not linked to a specific server.

On Exchange 2007 servers, when the test runs, it looks for a test mailbox on each server. The test mailbox can be on any store on that server. You need one test mailbox per server to run this test. If there are multiple test mailboxes on each server, the test uses the first mailbox it finds. By default, the test mailbox creation scripts create one test mailbox per store.

You can configure this test to collect tracking information to trace the test message that flows through the Exchange servers.

For Exchange 2007, you can use the Internal Mailbox Delivery Health test to monitor the sending and receiving of messages between mailboxes. For Exchange 2010 and later, you can use the Exchange Modern Message Delivery Health test.

Figure 1. A test message is sent from each server to every other server.

You must manually create test mailboxes and match the name to the mailbox mask specified in the test configuration. For more information, see Creating test mailboxes for Exchange .

Recommendations for Performance Optimization

For large organizations, select a subset of the servers to reduce the amount of traffic generated. For example, select one server per geographical region. You can also decrease the monitoring frequency.

For Exchange 2007 servers, create a test mailbox that matches the mailbox mask in at least one store on each server in the organization. However, it is recommended that you create a test mailbox in each store on each server.

For Exchange 2010 servers, create a test mailbox that matches the mailbox mask in at least one mounted mailbox database copy on each server in the organization. However, it is recommended that the test mailbox be created in each mailbox database on each server. When the test runs, it looks for a test mailbox on each server. The test mailbox is in a mailbox database. If there are multiple test mailbox boxes on each server, the test uses the first one it finds. By default, the test mailbox creation scripts create one test mailbox per mailbox database.

While the test is executing, storage groups and stores are enumerated in alphabetical order. If the test takes a long time to complete, you can create a test mailbox in the first storage group in the first store (in alphabetical order) on every server to speed up the query.

For example, you have a server called AMER-MBX-01 with the following stores:

•
First-Mailbox-Store (in storage group First-Storage-Group)
•
Second-Mailbox-Store (in storage group First-Storage-Group)
•
Third-Mailbox-Store (in storage group Second-Storage-Group)

If the mailbox mask specified in the test is the default mask (SOM_<ServerName>_<StorageGroupName>_<StoreName>, then the test looks for the following mailboxes for AMER-MBX-01 until it finds one that is accessible:

•
SOM_AMER-MBX-01_First-Storage-Group_First-Mailbox-Store
•
SOM_AMER-MBX-01_First-Storage-Group_Second-Mailbox-Store
•
SOM_AMER-MBX-01_Second-Storage-Group_Third-Mailbox-Store

For example, you have a server called AMER-MBX-01 containing Database1 and Database2. If the mailbox mask specified in the test is the default mask (SOM_<ServerName>_<DatabaseName>, then the test looks for the following mailboxes for AMER-MBX-01 until it finds one that is accessible:

•
SOM_AMER-MBX-01_Database1
•
SOM_AMER-MBX-01_Database2
<DatabaseName> token is optional.

All test messages sent are automatically deleted from the internal test mailboxes. But other mail, such as NDR messages, is not automatically deleted. You must manually clean out your test mailboxes periodically.

To enable this test to collect tracking information
•
From the All Exchange Servers tab, select the Collect message tracking information check box.
The tracking information is located in the Delivery details counter.

Exchange Internal Mailbox Delivery Health Test

For Exchange 2007 to Exchange 2013, you can use the Exchange Internal Mailbox Delivery Health Test to monitor the sending and receipt of messages between mailboxes in an Exchange organization. This test supports DAGs.

For Exchange 2010 and later, it is recommended that you run the Exchange Modern Message Delivery Health Test instead, especially in scenarios in which the CAS server is behind a load balancer.

Exchange External Message Delivery Health Test

For Exchange 2007 to Exchange 2013, you can use the Exchange External Message Delivery Health test to monitor the health of message delivery to and from an external target.

For Exchange 2010 and later, it is recommended that you run the Exchange Modern Message Delivery Health Test instead, especially in scenarios in which the CAS server is behind a load balancer.

This test tracks the time it takes a test email to leave your organization and the time it takes the message to return to the original server.

For this test, you must enter the names of:

•
Source mailbox to send a message to an SMTP address and receive replies from that address
•
Destination email address to indicate where test messages are sent

For more information about test prerequisites, see Unified Communications Diagnostics Deployment Guide.

About the test

This test targets your entire organization, not individual servers. You must create a test mailbox to run this test.

To monitor round-trip messages, the external mailbox must be configured to automatically bounce the message back to the original mailbox. You would enable the Round-Trip Delivery counter in the test.

All test messages sent are automatically deleted from the internal test mailbox. But any other mail, like NDR messages, are not automatically deleted. You may need to periodically clean out your test mailboxes.

By default, the Organization Exit counters are disabled because they are not fully supported when the source mailbox is hosted on Exchange 2013.The Round-trip Delivery counters are enabled because the external email account needs to be configured to automatically bounce the test message back to the originating mailbox.
