Exchange MailBox Test

This test automatically discovers all the mailboxes on a monitored Exchange 2000/2003 server, and reports the usage of each mailbox. Mailbox monitoring enables Exchange administrators to be proactively alerted when the mailbox usage grows close to the mailbox quota. In the long run, such a practice could deter mailbox users from storing unnecessary mails, thus automatically making room for important ones. 

This test is disabled by default. To enable the test, go to the enable / disable tests page using the menu sequence : Agents -> Tests -> Enable/Disable, pick Exchange the desired Component type, set Performance as the Test type, choose the test from the disabled tests list, and click on the < button to move the test to the ENABLED TESTS list.

Configurable parameters for the test
Parameters Description

Test Period

How often should the test be executed.


The IP address of the machine where the Exchange Server is installed.


The port number through which the Exchange server communicates.


By default, a "*" is displayed here, indicating that the test automatically discovers all the mailboxes configured for all the users on the Exchange server.

Measurements made by the test
Measurement Description Measurement Unit Interpretation

Exchange mailbox size

Indicates the current size of this mailbox.



Quota size

Indicates the maximum size up to which the mailbox can grow.



Exchange mailbox usage

Indicates the percentage of mailbox space that has been utilized currently.


This is computed as Mailbox_size/Quota_size*100. If the value of this measure is very high, it indicates that the mailbox is being over-utilized. If the situation is left unchecked, then soon the mail server will bounce off all new mails that are being delivered to the mailbox. You might want to clear unwanted mails from your mailbox to prevent such an occurrence.
