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" entry in the Sharing and collaboration permissions topic.


Parameter Required Type Description




The Name parameter specifies the name for the public folder.




The Confirm switch specifies whether to show or hide the confirmation prompt. How this switch affects the cmdlet depends on if the cmdlet requires confirmation before proceeding.

  • Destructive cmdlets (for example, Remove-* cmdlets) have a built-in pause that forces you to acknowledge the command before proceeding. For these cmdlets, you can skip the confirmation prompt by using this exact syntax: -Confirm:$false.

  • Most other cmdlets (for example, New-* and Set-* cmdlets) don't have a built-in pause. For these cmdlets, specifying the Confirm switch without a value introduces a pause that forces you acknowledge the command before proceeding.




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,




The EformsLocaleId parameter specifies the locale-specific version of the e-forms library. The valid input for the EformsLocaleId parameter is the string names listed in the Culture Name column in the Microsoft .NET Class Library class reference available at CultureInfo Class.

  • GUID

  • Distinguished name (DN)

  • Domain\Account

  • User principal name (UPN)

  • LegacyExchangeDN

  • SMTP address

  • Alias




The Path parameter specifies the location of the folder in the folder hierarchy, for example, \Legal\Cases.




The WhatIf switch simulates the actions of the command. You can use this switch to view the changes that would occur without actually applying those changes. You don't need to specify a value with this switch.
