Applies to: Exchange Online, Exchange Server 2016

This cmdlet is available in on-premises Exchange Server 2016 and in the cloud-based service. Some parameters and settings may be exclusive to one environment or the other.

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.

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

Get-MailPublicFolder [-Identity <MailPublicFolderIdParameter>] <COMMON PARAMETERS>

Get-MailPublicFolder [-Anr <String>] <COMMON PARAMETERS>

COMMON PARAMETERS: [-Credential <PSCredential>] [-DomainController <Fqdn>] [-Filter <String>] [-IgnoreDefaultScope <SwitchParameter>] [-ReadFromDomainController <SwitchParameter>] [-ResultSize <Unlimited>] [-SortBy <String>]

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*

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 "Public folders, mail-enabled" entry in the Sharing and collaboration 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 that's used to run this command. Typically, you use this parameter in scripts or when you need to provide different credentials that have the required permissions.

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.




This parameter is available only in on-premises Exchange 2016.

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 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 switch tells the command to ignore the default recipient scope setting for the Exchange Management Shell session, and to use the entire forest as the scope. This allows the command to access Active Directory objects that aren't currently available in the default scope.

Using the IgnoreDefaultScope switch 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 DN for the Identity parameter. Other forms of identification, such as alias or GUID, aren't accepted.




This parameter is available only in on-premises Exchange 2016.

The ReadFromDomainController switch specifies that information should be read from a domain controller in the user's domain. If you run the command Set-AdServerSettings -ViewEntireForest $true to include all objects in the forest and you don't use the ReadFromDomainController switch, it's possible that information will be read from a global catalog that has outdated information. When you use the ReadFromDomainController switch, multiple reads might be necessary to get the information. You don't have to specify a value with this switch.

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




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




The SortBy parameter specifies the property to sort the results by. You can sort by only one property at a time. The results are sorted in ascending order.

If the default view doesn't include the property you're sorting by, you can append the command with | Format-Table -Auto <Property1>,<Property2>... to create a new view that contains all of the properties that you want to see. Wildcards (*) in the property names are supported.

You can sort by the following properties:

  • Name

  • DisplayName

  • Alias

  • Id
