Use the Enable-MailPublicFolder cmdlet to mail-enable public folders.

Enable-MailPublicFolder -Identity <PublicFolderIdParameter> [-Confirm [<SwitchParameter>]] [-DomainController <Fqdn>] [-HiddenFromAddressListsEnabled <$true | $false>] [-Server <ServerIdParameter>] [-WhatIf [<SwitchParameter>]]

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.


Parameter Required Type Description




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 Confirm switch causes the command to pause processing and requires you to acknowledge what the command will do before processing continues. You don't have to specify a value with the Confirm switch.




The DomainController parameter specifies the fully qualified domain name (FQDN) of the domain controller that writes this configuration change to Active Directory.




The HiddenFromAddressListsEnabled parameter specifies whether the folder is hidden from address lists. Valid values are $true and $false. The default value is $false.




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 running 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) Mailbox server that has a mounted public folder store.




The WhatIf switch instructs the command to simulate the actions that it would take on the object. By using the WhatIf switch, you can view what changes would occur without having to apply any of those changes. You don't have to specify a value with the WhatIf switch.
