PRTG Manual: Exchange Mailbox (PowerShell) Sensor
The Exchange Mailbox (PowerShell) sensor monitors mailboxes of an Exchange server using Remote PowerShell.
It shows several states of a mailbox, for example:
- Total size of items in place
- Number of items in place
- Passed time since the last mailbox logon
Which channels the sensor actually shows might depend on the monitored device and the sensor setup.

- The parent device for this sensor must be the Exchange server (version 2010 or higher) that hosts the database you want to monitor.
- Requires credentials for Windows systems to be defined for the device you want to use the sensor on.
- Requires Remote PowerShell and Remote Exchange Management Shell on the target servers and PowerShell 2.0 on the probe system.
- Requires the FQDN of the Exchange server in the parent device settings.
- Requires elevated rights for the user of this sensor on the Exchange system. It is not sufficient to have administrator rights. For details, see the Knowledge Base: I have problems with the PowerShell Exchange sensors, what can I do? (solution (2) in the reply)
- Requires .NET 4.7.2 or later on the probe system.

You cannot add this sensor type to the Hosted Probe of a PRTG hosted by Paessler instance. If you want to use this sensor type, please add it to a remote probe device.
Requirement: Remote PowerShell and Remote Exchange Management Shell
This sensor type uses PowerShell commands. To monitor Exchange servers with this sensor, you have to enable Remote PowerShell and Remote Exchange Management Shell on the target servers that you want to monitor. Also ensure you have installed PowerShell 2.0 or later on your probe machine.
In larger environments, the default memory limit for the remote shell might be insufficient. This might result in the error message The WSMan provider host process did not return a proper response. In this case, increase the memory limit for Remote PowerShell.
For more information, see the Knowledge Base: How do I enable and use remote commands in Windows PowerShell?
Requirement: Fully Qualified Domain Name (FQDN)
To connect to Exchange servers, this sensor type needs the fully qualified domain name (FQDN). In the device settings of the Exchange server, provide the FQDN instead of the IP address.
For more information, see the Knowledge Base: I have problems with the PowerShell Exchange sensors, what can I do?
This sensor type requires the Microsoft .NET Framework version 4.7.2 or later to be installed on the computer running the PRTG probe, either on the local system (on every node, if on a cluster probe), or on the system running the remote probe. If the framework is missing, you cannot create this sensor.
For more information, see the Knowledge Base: Which .NET version does PRTG require?
The Add Sensor dialog appears when you manually add a new sensor to a device. It only shows the setting fields that are required for creating the sensor. Therefore, you will not see all setting fields in this dialog. You can change (nearly) all settings in the sensor's Settings tab later.
Select the Exchange server mailboxes you want to monitor. PRTG creates one sensor for each mailbox you choose in the Add Sensor dialog. The settings you choose will be valid for all sensors that you create when you finish this dialog.
The following settings for this sensor differ in the Add Sensor dialog in comparison to the sensor's Settings tab.
Sensor Settings |
|
---|---|
Mailboxes |
Select the mailboxes you want to add a sensor for. You see a list with the names of all items that are available to monitor. Add check marks in front of the respective lines to select the desired items. PRTG creates one sensor for each selection. You can also use the check box in the table head to select and deselect all items. |
On the details page of a sensor, click the Settings tab to change its settings.
Usually, a sensor connects to the IP Address or DNS Name of the parent device where you created this sensor. See the Device Settings for details. For some sensor types, you can define the monitoring target explicitly in the sensor settings. See below for details on available settings.
Basic Sensor Settings |
|
---|---|
Sensor Name |
Enter a meaningful name to identify the sensor. By default, PRTG shows this name in the device tree, as well as in alarms, logs, notifications, reports, maps, libraries, and tickets. |
Parent Tags |
Shows Tags that this sensor inherits from its parent device, group, and probe. This setting is shown for your information only and cannot be changed here. |
Tags |
Enter one or more Tags, separated by spaces or commas. You can use tags to group sensors and use tag–filtered views later on. Tags are not case sensitive. We recommend that you use the default value. You can add additional tags to the sensor if you like. Other tags are automatically inherited from objects further up in the device tree. These are visible above as Parent Tags.
|
Priority |
Select a priority for the sensor. This setting determines where the sensor is placed in sensor lists. Top priority is at the top of a list. Choose from one star (low priority) to five stars (top priority). |
Sensor Settings |
|
---|---|
Mailbox Name |
Shows the name of the monitored mailbox. Once a sensor is created, you cannot change this value. It is shown for reference purposes only. If you need to change this, please add the sensor anew. |
Sensor Result |
Define what PRTG will do with the sensor results. Choose between:
|
Sensor Display |
|
---|---|
Primary Channel |
Select a channel from the list to define it as the primary channel. In the device tree, the last value of the primary channel will always be displayed below the sensor's name. The available options depend on what channels are available for this sensor.
|
Graph Type |
Define how different channels will be shown for this sensor.
|
Stack Unit |
This setting is only available if stacked graphs are selected above. Choose a unit from the list. All channels with this unit will be stacked on top of each other. By default, you cannot exclude single channels from stacking if they use the selected unit. However, there is an advanced procedure to do so. |
By default, all following settings are inherited from objects higher in the hierarchy and should be changed there, if necessary. Often, best practice is to change them centrally in the Root group's settings, see section Inheritance of Settings for more information. To change a setting only for this object, disable inheritance by clicking the button next to inherit from under the corresponding setting name. You will then see the options described below.
Scanning Interval |
|
---|---|
Click |
|
Scanning Interval |
Select a scanning interval (seconds, minutes, or hours) from the list. The scanning interval determines the time the sensor waits between two scans. You can change the available intervals in the system administration on PRTG on premises installations. |
If a Sensor Query Fails |
Define the number of scanning intervals that a sensor has time to reach and check a device again in case a sensor query fails. The sensor can try to re-reach and check a device several times, depending on the option you select here, before it will be set to a Down status. This helps you avoid false alarms if the monitored device has only temporary issues. For previous scanning intervals with failed requests, the sensor will show a Warning status. Choose between:
|
Schedules, Dependencies, and Maintenance Window |
|
---|---|
|
|
Schedule |
Select a schedule from the list. Schedules can be used to monitor for a certain time span (days, hours) every week. With the period list option it is also possible to pause monitoring for a specific time span. You can create new schedules and edit existing ones in the account settings.
|
Maintenance Window |
Specify if you want to set up a one-time maintenance window. During a "maintenance window" period, this object and all child objects will not be monitored. They will be in a Paused status instead. Choose between:
|
Maintenance Begins |
This field is only visible if you enabled the maintenance window above. Use the date time picker to enter the start date and time of the maintenance window. |
Maintenance Ends |
This field is only visible if you enabled the maintenance window above. Use the date time picker to enter the end date and time of the maintenance window. |
Dependency Type |
Define a dependency type. Dependencies can be used to pause monitoring for an object depending on the status of another. You can choose between:
|
Dependency |
This field is only visible if the Select object option is enabled above. Click on the reading-glasses and use the object selector to choose an object on which the current sensor will depend. |
Dependency Delay (Sec.) |
Define a time span in seconds for a dependency delay. After the master object for this dependency goes back to Up status, PRTG will start monitoring the depending objects after this extra delayed. This can help to avoid false alarms, for example, after a server restart, by giving systems more time for all services to start up. Please enter an integer value.
|
Access Rights |
|
---|---|
Click |
|
User Group Access |
Define which user group(s) will have access to the object you're editing. A table with user groups and types of access rights is shown. It contains all user groups from your setup. For each user group, you can choose from the following access rights:
You can create new user groups in the System Administration—User Groups settings. To automatically set all objects further down in the hierarchy to inherit this object's access rights, set a check mark for the Revert children's access rights to inherited option.
