Exchange 2010

Applies to: Exchange Server 2010 SP2, Exchange Server 2010 SP3

Topic Last Modified: 2015-03-09

Use the Get-ThrottlingPolicyAssociation cmdlet to view the relationship between objects and their associated throttling policies. The object can be a user with a mailbox, a user without a mailbox, a contact, or a computer account.

Get-ThrottlingPolicyAssociation [-Identity <ThrottlingPolicyAssociationIdParameter>] [-Credential <PSCredential>] [-DomainController <Fqdn>] [-Filter <String>] [-IgnoreDefaultScope <SwitchParameter>] [-Organization <OrganizationIdParameter>] [-OrganizationalUnit <OrganizationalUnitIdParameter>] [-ReadFromDomainController <SwitchParameter>] [-ResultSize <Unlimited>] [-SortBy <String>]

Get-ThrottlingPolicyAssociation [-Anr <String>] [-Credential <PSCredential>] [-DomainController <Fqdn>] [-Filter <String>] [-IgnoreDefaultScope <SwitchParameter>] [-Organization <OrganizationIdParameter>] [-OrganizationalUnit <OrganizationalUnitIdParameter>] [-ReadFromDomainController <SwitchParameter>] [-ResultSize <Unlimited>] [-SortBy <String>]

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 "Client throttling settings" entry in the Client Access Permissions topic.


Parameter Required Type Description




The Anr parameter specifies a string on which to perform an ambiguous name resolution (ANR) search. You can specify a partial string and search for objects with an attribute that matches that string. The default attributes searched are:

  • CommonName (CN)

  • DisplayName

  • FirstName

  • LastName

  • Alias




The Credential parameter specifies the user name and password to use to access Active Directory.

This parameter requires the creation and passing of a credential object. This credential object is created by using the Get-Credential cmdlet. For more information, see Get-Credential.




The DomainController parameter specifies the fully qualified domain name (FQDN) of the domain controller that retrieves data from Active Directory.




The Filter parameter indicates the OPath filter used to filter recipients.

For more information about the filterable properties, see Filterable Properties for the -Filter Parameter.




The Identity parameter specifies the object to query to see its throttling policy associations. The object can be a user with a mailbox, a user without a mailbox, a contact, or a computer account.




The IgnoreDefaultScope parameter instructs the command to ignore the default recipient scope setting for the Exchange Management Shell session and use the entire forest as the scope. This allows the command to access Active Directory objects that aren't currently in the default scope. Using the IgnoreDefaultScope parameter introduces the following restrictions:

  • You can't use the DomainController parameter. The command uses an appropriate global catalog server automatically.

  • You can only use the distinguished name (DN) for the Identity parameter. Other forms of identification, such as alias or GUID, aren't accepted.

  • You can't use the OrganizationalUnit and Identity parameters together.

  • You can't use the Credential parameter.




The Organization parameter specifies the organization that the object specified by the Identity parameter is in.




The OrganizationalUnit parameter specifies an organizational unit (OU) and is used to limit the results. If you use this parameter, you only get mailboxes in the container that you specify. You can use either the OU or the domain name. If you use the OU, you must specify the canonical name of the OU.




The ReadFromDomainController parameter specifies that the user information is read from a domain controller in the user's domain. If you set the recipient scope to include all recipients in the forest and don't use this parameter, it's possible that the user information is read from a global catalog with outdated information. If you use this parameter, multiple reads might be necessary to get the information.

By default, the recipient scope is set to the domain that hosts your servers that run Exchange.




The ResultSize parameter specifies the maximum number of results to return. If you want to return all mailboxes that match the query, use unlimited for the value of this parameter. The default value is 1000.




The SortBy parameter specifies the attribute by which to sort the results. You can sort by only one attribute at a time. You can sort by the following attributes:

  • Alias

  • Display name

  • Name

The results are sorted in ascending order.

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.

This example returns a list of all the mailboxes in your organization in the Users OU.

Get-ThrottlingPolicyAssociation -OrganizationalUnit Users

This example returns all the mailboxes that resolve from the ambiguous name resolution search on the string "Chr" that are in the domain DC01. This example returns mailboxes for users such as Chris Ashton, Christian Hess, and Christa Geller.

Get-ThrottlingPolicyAssociation -Anr Chr -DomainController DC01
