Applies to: Exchange Server 2016

This cmdlet is available only in on-premises Exchange Server 2016.

Use the Add-GlobalMonitoringOverride cmdlet to override the thresholds and parameters used by the probes, monitors, and responders on all Exchange 2013 servers in an Exchange Server 2013 environment. The cmdlet enables monitoring changes and threshold tuning to the environment.

For information about the parameter sets in the Syntax section below, see Syntax.

Add-GlobalMonitoringOverride [-Duration <EnhancedTimeSpan>] <COMMON PARAMETERS>
Add-GlobalMonitoringOverride -ApplyVersion <Version> <COMMON PARAMETERS>
COMMON PARAMETERS: -Identity <String> -ItemType <Probe | Monitor | Responder | Maintenance> -PropertyName <String> -PropertyValue <String> [-Confirm [<SwitchParameter>]] [-DomainController <Fqdn>] [-WhatIf [<SwitchParameter>]]

This example adds a global monitoring override that disables the OnPremisesInboundProxy probe for 30 days for all servers running version 15.00.0847.32.

Add-GlobalMonitoringOverride -Identity "FrontendTransport\OnPremisesInboundProxy" -PropertyName Enabled -PropertyValue 0 -Duration 30.00:00:00 -ItemType Probe -ApplyVersion "15.00.0847.32"

This example adds a global monitoring override that disables the StorageLogicalDriveSpaceEscalate responder for 21 days for all servers running version 15.00.0847.32.

Add-GlobalMonitoringOverride -Identity "MailboxSpace\StorageLogicalDriveSpaceEscalate" -PropertyName Enabled -PropertyValue 0 -Duration 21.00:00:00 -ItemType Responder -ApplyVersion "15.00.0847.32"

You need to be assigned permissions before you can run this cmdlet. Although all parameters for this cmdlet are listed in this topic, you may not have access to some parameters if they're not included in the permissions assigned to you. To see what permissions you need, see the "Shell infrastructure permissions" section in the Exchange infrastructure and PowerShell permissions topic.


Parameter Required Type Description




The ApplyVersion parameter specifies the version of override. The valid input for this parameter is a number in the format 15.00.xxxx.xxx.




The Identity parameter specifies the identity of the server to access.




The ItemType parameter specifies the item type that you want to designate the new property. It can be any of the following values:

  • Probe

  • Monitor

  • Responder




The PropertyName parameter specifies the property you want to override.




The PropertyValue parameter specifies the new value of the property you are trying to override.




The Confirm switch specifies whether to show or hide the confirmation prompt. How this switch affects the cmdlet depends on if the cmdlet requires confirmation before proceeding.

  • Destructive cmdlets (for example, Remove-* cmdlets) have a built-in pause that forces you to acknowledge the command before proceeding. For these cmdlets, you can skip the confirmation prompt by using this exact syntax: -Confirm:$false.

  • Most other cmdlets (for example, New-* and Set-* cmdlets) don't have a built-in pause. For these cmdlets, specifying the Confirm switch without a value introduces a pause that forces you acknowledge the command before proceeding.




The DomainController parameter specifies the domain controller that's used by this cmdlet to read data from or write data to Active Directory. You identify the domain controller by its fully qualified domain name (FQDN). For example, dc01.contoso.com.

The DomainController parameter isn't supported on Edge Transport servers. An Edge Transport server uses the local instance of Active Directory Lightweight Directory Services (AD LDS) to read and write data.




The Duration parameter specifies the length of time to keep the monitoring override.

To specify a value, enter it as a time span: dd.hh:mm:ss where dd = days, hh = hours, mm = minutes, and ss = seconds.

For example, 30.10:00:00 specifies 30 days and 10 hours.




The WhatIf switch simulates the actions of the command. You can use this switch to view the changes that would occur without actually applying those changes. You don't need to specify a value with this switch.

To see the input types that this cmdlet accepts, see Cmdlet Input and Output Types. If the Input Type field for a cmdlet is blank, the cmdlet doesn’t accept input data.

To see the return types, which are also known as output types, that this cmdlet accepts, see Cmdlet Input and Output Types. If the Output Type field is blank, the cmdlet doesn’t return data.
