Examples

EXAMPLE 1

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.

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

EXAMPLE 2

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.

Copy Code
Set-ThrottlingPolicy RemoteSiteUserPolicy -PowerShellMaxConcurrency 3 -PowerShellMaxCmdletQueueDepth 12

EXAMPLE 3

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.

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

Detailed Description

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.

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.

If users attempt to make more concurrent requests than their policy allows, the new connection attempt fails. However, the existing connections remain valid. The OwaMaxConcurrency parameter has a valid range from 0 through 2147483647 inclusive. The default value is 5. To indicate that the number of concurrent connections should be unthrottled (no limit), this value should be set to $null.

OwaRechargeRate

Optional

Microsoft.Exchange.Data.Unlimited

The OwaRechargeRate parameter specifies the rate at which an Outlook Web App user's budget is charged (budget grows by) during the budget time.

OwaVoiceCutoffBalance

PowerShellMaxCmdletQueueDepth

Optional

Microsoft.Exchange.Data.Unlimited

The PowerShellMaxCmdletQueueDepth parameter specifies the number of operations allowed to be executed by the user. This value directly affects the behavior of the PowerShellMaxCmdlets and PowerShellMaxConcurrency parameters. For example, the PowerShellMaxConcurrency parameter consumes at least two operations defined by the PowerShellMaxCmdletQueueDepth parameter but additional operations are also consumed by per cmdlet execution. The number of operations depends on the cmdlets that are executed. We recommend that the value for the PowerShellMaxCmdletQueueDepth parameter be at least three times larger than the value of the PowerShellMaxConcurrency parameter. This parameter won't affect Exchange Administration Center operations or Exchange Web Services operations.

PowerShellMaxCmdlets

Optional

Microsoft.Exchange.Data.Unlimited

The PowerShellMaxCmdlets parameter specifies the number of cmdlets that can be executed within a specific time period before their execution is stopped. The value specified by this parameter should be more than the value specified by the ExchangeMaxCmdlets parameter.

  • 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

The time period used for this limit is specified by the PowerShellMaxDestructiveCmdletsTimePeriod parameter. Both values should be set at the same time. This feature isn't enabled by default. For more information, see the example in this topic.

PowerShellMaxDestructiveCmdletsTimePeriod

Optional

Microsoft.Exchange.Data.Unlimited

The PowerShellMaxDestructiveCmdletsTimePeriod parameter specifies the time period, in seconds, that the throttling policy uses to determine how many destructive cmdlets can be run. You set a value for this parameter when set the PowerShellMaxDestructiveCmdlets parameter. Both values should be set at the same time. 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.

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.

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