Use the Get-MailPublicFolder cmdlet to retrieve mail-related information about mail-enabled public folders. If you want information about the basic (not mail-related) settings of mail-enabled public folders, use the Get-PublicFolder cmdlet instead.

Get-MailPublicFolder [-Identity <MailPublicFolderIdParameter>] [-Credential <PSCredential>] [-DomainController <Fqdn>] [-Filter <String>] [-IgnoreDefaultScope <SwitchParameter>] [-ReadFromDomainController <SwitchParameter>] [-ResultSize <Unlimited>] [-Server <ServerIdParameter>] [-SortBy <String>]

Get-MailPublicFolder [-Anr <String>] [-Credential <PSCredential>] [-DomainController <Fqdn>] [-Filter <String>] [-IgnoreDefaultScope <SwitchParameter>] [-ReadFromDomainController <SwitchParameter>] [-ResultSize <Unlimited>] [-Server <ServerIdParameter>] [-SortBy <String>]

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




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 GUID or public folder name that represents a specific public folder. You can also include the path using the format \TopLevelPublicFolder\PublicFolder.

You can omit the parameter label so that only the public folder name or GUID is supplied.




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't use the Anr and Identity parameters together.
  • You can't use the Credential parameter.




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 if you 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 Microsoft Exchange.




The ResultSize parameter specifies the maximum number of results to return.




The Server parameter specifies the identity of the server to perform the operation from. If a server isn't specified, the command checks whether the local server is a Mailbox server with a public folder store. If it is, the folder is created locally. If it isn't, the command finds the closest (by site cost) computer running Microsoft Exchange Server 2010 that has the Mailbox server role installed and that has a mounted public folder store.




The SortBy parameter specifies the attribute by which to sort the results. Sorting is done one attribute at a time. The results are sorted in ascending order.

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 "Mail-enabled public folder" entry in the Mailbox Permissions topic.

Error Description


Exceptions Description


This example returns the information for up to 100 mail-enabled public folders. In this example, the output of the Get-MailPublicFolder command is piped to the Format-List command so that all the available information is displayed in the result.

Get-MailPublicFolder -ResultSize 100 | Format-List

This example returns information for the mail-enabled public folder Reports that resides in the Marketing top-level public folder.

Get-MailPublicFolder -Identity \Marketing\Reports 

This example returns all mail-enabled public folders that begin with the word Marketing by using the Anr parameter.

Get-MailPublicFolder -Anr Marketing
