Reference

Module:: ExchangePowerShell

Applies to:: Exchange Server 2010, Exchange Server 2013, Exchange Server 2016, Exchange Server 2019, Exchange Online

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

Use the New-MailboxFolder cmdlet to create folders in your own mailbox. Administrators can't use this cmdlet to create folders in other mailboxes (the cmdlet is available only from the MyBaseOptions user role).

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

Syntax

New-MailboxFolder
   [-Name] <String>
   -Parent <MailboxFolderIdParameter>
   [-Confirm]
   [-DomainController <Fqdn>]
   [-WhatIf]
   [<CommonParameters>]

Description

If no parent folder is specified, the cmdlet creates a mail folder in the root folder hierarchy of the mailbox. If the mailbox isn't specified, the cmdlet creates the folder in the mailbox of the user currently running the task. When run, the cmdlet returns the new folder name and the folder path as the output.

You need to be assigned permissions before you can run this cmdlet. Although this topic lists all parameters for the cmdlet, you may not have access to some parameters if they're not included in the permissions assigned to you. To find the permissions required to run any cmdlet or parameter in your organization, see Find the permissions required to run any Exchange cmdlet. .

Examples

Example 1

New-MailboxFolder -Parent :\Inbox -Name Personal

This example creates the folder named Personal under the Inbox folder of your own mailbox.

Example 2

New-MailboxFolder -Parent :\ -Name Personal

This example creates the folder named Personal in the root folder hierarchy of your own mailbox.

Parameters

-Confirm

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.

-DomainController

This parameter is available only in on-premises Exchange.

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.

Type:	String
Position:	1
Default value:	None
Required:	True
Accept pipeline input:	False
Accept wildcard characters:	False
Applies to:	Exchange Server 2010, Exchange Server 2013, Exchange Server 2016, Exchange Server 2019, Exchange Online

-Parent

The Parent parameter specifies where to create the new mailbox folder. The syntax is [MailboxID]:\[ParentFolder][\SubFolder].

You can only run this cmdlet on your own mailbox, so you don't need to (or can't) specify a MailboxID value.

To specify the root folder hierarchy of your own mailbox, use the value :\.

For the value of MailboxID, you can use any value that uniquely identifies the mailbox. For example:

Name
Alias
Distinguished name (DN)
Canonical DN
Domain\Username
Email address
GUID
LegacyExchangeDN
SamAccountName
User ID or user principal name (UPN)

If you don't specify the parent folder, the command creates the folder in the root folder hierarchy of the specified mailbox.

Example values for this parameter are john@contoso.com:, John:\Inbox

Type:	MailboxFolderIdParameter
Position:	Named
Default value:	None
Required:	True
Accept pipeline input:	True
Accept wildcard characters:	False
Applies to:	Exchange Server 2010, Exchange Server 2013, Exchange Server 2016, Exchange Server 2019, Exchange Online

-WhatIf

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.
