Exchange Mailboxes Test

This test reports critical statistics pertaining to each mailbox on an Exchange server, such as the mailbox size, the mailbox quota, the size and number of deleted items, etc., and also reveals how effectively the mailbox has been utilized. 

Target of the test : A server configured with the Mailbox role

Agent deploying the test : An internal agent

Outputs of the test : One set of results for each mailbox on the server monitored.

Configurable parameters for the test
Parameters Description

Test Period

How often should the test be executed.


The IP address of the machine configured with the Mailbox server role.


The port number through which the Mailbox server communicates. The default is 6001.


The Exchange Management Shell is a command-line management interface, built on Windows PowerShell which enables you to administer every part of Microsoft Exchange. This test uses the Exchange management shell to run scripts and collect the desired performance metrics from the Exchange server. By default, the test auto-discovers the location of the Exchange management shell and thus, automatically loads the Exchange management shell snap-in (exshell.psc1) for script execution. This is why, the XchgeXtensionShellPath is set to none by default.


Specify the name of the target Exchange server.

DD Frequency

Refers to the frequency with which detailed diagnosis measures are to be generated for this test. The default is 1:1. This indicates that, by default, detailed measures will be generated every time this test runs, and also every time the test detects a problem. You can modify this frequency, if you so desire. Also, if you intend to disable the detailed diagnosis capability for this test, you can do so by specifying none against DD frequency.

Detailed Diagnosis

To make diagnosis more efficient and accurate, the eG Enterprise embeds an optional detailed diagnostic capability. With this capability, the eG agents can be configured to run detailed, more elaborate tests as and when specific problems are detected. To enable the detailed diagnosis capability of this test for a particular server, choose the On option. To disable the capability, click on the Off option.

The option to selectively enable/disable the detailed diagnosis capability will be available only if the following conditions are fulfilled:

  • The eG manager license should allow the detailed diagnosis capability
  • Both the normal and abnormal frequencies configured for the detailed diagnosis measures should not be 0.
Measurements made by the test
Measurement Description Measurement Unit Interpretation

Deleted item count

Indicates the number of deleted messages in this mailbox.



Total deleted item size

Indicates the total size of all deleted items in this mailbox.



Total items

Indicates the total number of messages in this mailbox.




Indicates the total size of this mailbox.




Indicates the allocated size of this mailbox.


If the mailbox Size is dangerously close to the Quota, you may want to either reset the quota or delete unnecessary messages from the mailbox to free up space. This needs to be done so that the mailbox does not violate its quota, causing mails to bounce.

Mailbox usage

Indicates the mailbox usage.
