This example modifies a throttling policy so that users associated with this policy can have a maximum of four concurrent requests running in Exchange Web Services.

$a = Get-ThrottlingPolicy RemoteSiteUserPolicy
$a | Set-ThrottlingPolicy -EwsMaxConcurrency 4

This example modifies a throttling policy so that it restricts the number of connections for a user to three. The users associated with this policy are only able to create three Exchange Management Shell sessions. This policy also restricts to three the number of Exchange Administration Center operations or Exchange Web Services operations that can be executed at the same time. In addition, the PowerShellMaxCmdletQueueDepth parameter specifies that 12 operations maximum are allowed to be executed by the user.

Set-ThrottlingPolicy RemoteSiteUserPolicy -PowerShellMaxConcurrency 3 -PowerShellMaxCmdletQueueDepth 12

This example modifies a throttling policy so that it restricts a user to be able to execute only 10 destructive cmdlets in 60 seconds. If the users associated with this policy exceed this number, the cmdlet pipeline execution is stopped with a throttling error message. The user needs to wait for, and then resubmit the execution of cmdlets on the open connection.

Set-ThrottlingPolicy <ThrottlingPolicyName> -PowerShellMaxDestructiveCmdlets 10 -PowerShellMaxDestructiveCmdletsTimePeriod 60

Throttling policy settings are stored in Active Directory.

By default, there is one default user throttling policy named GlobalThrottlingPolicy with a throttling scope of Global. Microsoft Setup creates this policy when you install the Client Access server role. You shouldn't replace, re-create, or remove the existing default throttling policy. However, you can edit any additional throttling policies with the scope of Organization or Regular if you want to change your user throttling settings. You can create polices with the scope of Organization or Regular using the New-ThrottlingPolicy cmdlet.

For more information about how to control the resources consumed by individual users, see Exchange workload management.

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 "User throttling" entry in the Server health and performance permissions topic.

Microsoft.Exchange.Data.Unlimited

The ImapRechargeRate parameter specifies the rate at which the IMAP user's budget is charged (budget grows by) during the budget time.

IsServiceAccount

Optional

System.Management.Automation.SwitchParameter

The IsServiceAccount switch specifies whether you want the user accounts associated with this policy to be moderated by the per-user thresholds specified by this policy, and also by additional throttling based on the health of system resources, such as overall CPU usage.

This value is set to $false by default.

You may want to set this value to $true if you intend to associate this policy with user accounts that require higher throttling limits. An account that might require higher throttling limits is a service account that performs a lot of non-interactive work (for example, service accounts that perform IMAP mailbox migrations or nightly Windows PowerShell tasks)

By setting the IsServiceAccount switch to $true, work done by these accounts is moderated by the higher user throttling settings that you configure using the user throttling policy, but is slowed if resources start getting unhealthy.

MessageRateLimit

Optional

Microsoft.Exchange.Data.Unlimited

The MessageRateLimit parameter specifies the number of messages per minute that can be submitted to transport. For messages submitted through the Mailbox server role (using Microsoft Outlook, Microsoft Office Outlook Web App, Exchange ActiveSync, or Exchange Web Services), this results in the deferral of messages until the quota for the user is available. Specifically, messages appear in the Outbox or Drafts folder for longer periods of time when users submit messages at a rate greater than the MessageRateLimit parameter.

For POP or IMAP clients submitting messages directly to transport using SMTP, clients receive a transient error if they submit at a rate that exceeds the MessageRateLimit parameter. Exchange attempts to connect and send the messages at a later time.

The PowerShellMaxConcurrency parameter specifies different information depending on context:

  • In the context of Remote PowerShell, the PowerShellMaxConcurrency parameter specifies the maximum number of Remote PowerShell sessions that a Remote PowerShell user can have open at the same time.

  • In the context of Exchange Web Services, the PowerShellMaxConcurrency parameter specifies the number of concurrent cmdlet executions that a user can have at the same time.

This parameter value doesn't necessarily correlate to the number of browsers opened by the user.

PowerShellMaxDestructiveCmdlets

Optional

Microsoft.Exchange.Data.Unlimited

The PowerShellMaxDestructiveCmdlets parameter specifies the number of destructive cmdlets that can be executed within a specific time period before their execution is stopped. Destructive cmdlets are cmdlets that can make significant changes to user data and configuration settings in your Exchange organization. Throttling these cmdlets may help prevent accidental data loss. The following cmdlets are designated as destructive:

  • Disable-Mailbox

  • Move-ActiveMailboxDatabase

  • Remove-AcceptedDomain

  • Remove-Mailbox

  • Remove-MailUser

  • Remove-Organization

  • Remove-SecondaryDomain

For more information, see the description for the PowerShellMaxDestructiveCmdlets parameter.

PowerShellMaxOperations

Optional

Microsoft.Exchange.Data.Unlimited

The PowerShellMaxOperations parameter specifies the protocol-level operations used to send and receive data. If the execution of a cmdlet results in a significant number of operations (for example, if there is a lot of input/output occurring), throttling may occur. The default setting is Unlimited.

PowerShellMaxRunspaces

Optional

Microsoft.Exchange.Data.Unlimited

The PowerShellMaxRunspaces parameter specifies the number of concurrent Windows PowerShell sessions that a user is allowed to have. The default setting is Unlimited.

PowerShellMaxRunspacesTimePeriod

Optional

Microsoft.Exchange.Data.Unlimited

The PowerShellMaxRunspacesTimePeriod parameter specifies the time period, in seconds, that the throttling policy uses to determine how many Windows PowerShell sessions can be run. You set this value when you set the PowerShellMaxRunspaces parameter.

PowerShellMaxTenantConcurrency

Optional

Microsoft.Exchange.Data.Unlimited

The PowerShellMaxTenantConcurrency parameter limits the number of concurrent Windows PowerShell connections per tenant organization. By default, the limit for concurrent Windows PowerShell connections per tenant organization is set to 9. If users in a tenant organization try to make more concurrent requests than the limit set by the PowerShellMaxTenantConcurrency parameter, the new connection attempt fails. However, the existing connections remain valid. This limit is enforced even if a single user hasn't exceeded the per-user limit set by the PowerShellMaxConcurrency parameter. The PowerShellMaxTenantConcurrency parameter has a valid range from 0 through 100 inclusive. To indicate that the number of concurrent connections should be unthrottled (no limit), this value should be set to $null.

NoteNote:
This property can only be set for the default throttling policy.

The PswsMaxConcurrency parameter specifies how many concurrent connections a Windows PowerShell Web Services user can have against an Exchange server at one time. A connection is held from the moment a request is received until a response is sent in its entirety to the requestor. If users attempt to make more concurrent requests than their policy allows, the new connection attempt fails. However, the existing connections remain valid.

This parameter has a default value of 18. To indicate that the number of concurrent connections should be unthrottled (no limit), this value should be set to $null.

The RcaCutoffBalance parameter specifies the resource consumption limits for a user before that user is completely blocked from performing operations on a specific component.

RcaMaxBurst

Optional

Microsoft.Exchange.Data.Unlimited

The RcaMaxBurst parameter specifies the amount of time that a user can consume an elevated amount of resources before being throttled. This is measured in milliseconds. This value is set separately for each component.

RcaMaxConcurrency

Optional

Microsoft.Exchange.Data.Unlimited

The RcaMaxConcurrency parameter specifies how many concurrent connections an RPC Client Access user can have against a server running Exchange 2013 at one time. A connection is held from the moment a request is received until the connection is closed or the connection is otherwise disconnected (for example, if the user goes offline). If users attempt to make more concurrent requests than their policy allows, the new connection attempt fails. However, the existing connections remain valid. The RcaMaxConcurrency parameter has a valid range from 0 through 2147483647 inclusive. The default value is 20. To indicate that the number of concurrent connections should be unthrottled (no limit), this value should be set to $null.

RcaRechargeRate

Optional

Microsoft.Exchange.Data.Unlimited

The RcaRechargeRate parameter specifies the rate at which the user budget is charged (budget grows by) during the budget time.

RecipientRateLimit

Optional
