New-MailUser
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-MailUser cmdlet to create mail users. Mail users (also known as mail-enabled users) have email addresses and accounts in the Exchange organization, but they don't have Exchange mailboxes. Email messages sent to mail users are delivered to the specified external email address.
For information about the parameter sets in the Syntax section below, see Exchange cmdlet syntax.

[<CommonParameters>] Description
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-MailUser -Name "Ed Meadows" -ExternalEmailAddress ed@tailspintoys.com -MicrosoftOnlineServicesID ed@contoso.com -Password (Get-Credential).passwordThis example creates a new mail user for Ed Meadows in the contoso.com cloud-based organization. The mail user gives Ed an account and email address in the contoso.com domain, but messages sent to Ed are delivered to his tailspintoys.com email address.
Parameters
-Alias
The Alias parameter specifies the Exchange alias (also known as the mail nickname) for the recipient. This value identifies the recipient as a mail-enabled object, and shouldn't be confused with multiple email addresses for the same recipient (also known as proxy addresses). A recipient can have only one Alias value. The maximum length is 64 characters.
The Alias value can contain letters, numbers and the following characters:
- !, #, %, *, +, -, /, =, ?, ^, _, and ~.
- $, &, ', `, {, }, and | need to be escaped (for example
-Alias what`'snew) or the entire value enclosed in single quotation marks (for example,-Alias 'what'snew'). The & character is not supported in the Alias value for Microsoft Entra Connect synchronization. - Periods (.) must be surrounded by other valid characters (for example,
help.desk). - Unicode characters U+00A1 to U+00FF.
When you create a recipient without specifying an email address, the Alias value you specify is used to generate the primary email address (alias@domain). Supported Unicode characters are mapped to best-fit US-ASCII text characters. For example, U+00F6 (ö) is changed to oe in the primary email address.
If you don't use the Alias parameter when you create a recipient, the value of a different required parameter is used for the Alias property value:
- Recipients with user accounts (for example, user mailboxes, and mail users): The left side of the MicrosoftOnlineServicesID or UserPrincipalName parameter is used. For example, helpdesk@contoso.onmicrosoft.com results in the Alias property value
helpdesk. - Recipients without user accounts (for example, room mailboxes, mail contacts, and distribution groups): The value of the Name parameter is used. Spaces are removed and unsupported characters are converted to question marks (?).
If you modify the Alias value of an existing recipient, the primary email address is automatically updated only in environments where the recipient is subject to email address policies (the EmailAddressPolicyEnabled property is True for the recipient).
The Alias parameter never generates or updates the primary email address of a mail contact or a mail user.
| Type: | String |
| Position: | Named |
| Default value: | None |
| Required: | False |
| Accept pipeline input: | False |
| Accept wildcard characters: | False |
| Applies to: | Exchange Server 2010, Exchange Server 2013, Exchange Server 2016, Exchange Server 2019, Exchange Online, Exchange Online Protection |
-ArbitrationMailbox
This parameter is available only in on-premises Exchange.
The ArbitrationMailbox parameter specifies the arbitration mailbox that's used to manage the moderation process for this recipient. You can use any value that uniquely identifies the arbitration mailbox. For example:
- Name
- Alias
- Distinguished name (DN)
- Canonical DN
- Domain\Username
- Email address
- GUID
- LegacyExchangeDN
- SamAccountName
- User ID or user principal name (UPN)
| Type: | MailboxIdParameter |

-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.

| Required: | False |
| Accept pipeline input: | False |
| Accept wildcard characters: | False |

-DisplayName
The DisplayName parameter specifies the display name of the mail user. The display name is visible in the Exchange admin center, in address lists, and in Outlook. The maximum length is 256 characters. If the value contains spaces, enclose the value in quotation marks (").
If you don't use the DisplayName parameter, the value of the Name parameter is used for the display name.

-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: | Fqdn |

-ExternalEmailAddress
The ExternalEmailAddress parameter specifies the target email address of the mail contact or mail user. By default, this value is used as the primary email address of the mail contact or mail user.
In on-premises environments, you can use the PrimarySMTPAddress parameter to set the primary email address to a different value. However, we recommend this only in cross-forest environments.
| Type: | ProxyAddress |
| Position: | Named |
| Default value: | None |
| Required: | True |
| Accept pipeline input: | False |

The FederatedIdentity parameter associates an on-premises Active Directory user with a user in the cloud.
| Type: | String |
| Position: | Named |

| Position: | Named |
| Default value: | None |
| Required: | False |
| Accept pipeline input: | False |
| Accept wildcard characters: | False |
| Applies to: | Exchange Online, Exchange Online Protection |
-ImmutableId
The ImmutableId parameter is used by GAL synchronization (GALSync) and specifies a unique and immutable identifier in the form of an SMTP address for an Exchange mailbox used for federated delegation when requesting Security Assertion Markup Language (SAML) tokens. If federation is configured for this mailbox and you don't set this parameter when you create the mailbox, Exchange creates the value for the immutable ID based upon the mailbox's ExchangeGUID and the federated account namespace, for example, 7a78e7c8-620e-4d85-99d3-c90d90f29699@mail.contoso.com.
You need to set the ImmutableId parameter if Active Directory Federation Services (AD FS) is deployed to allow single sign-on into an off-premises mailbox and AD FS is configured to use a different attribute than ExchangeGUID for sign-on token requests. Both, Exchange and AD FS must request the same token for the same user to ensure proper functionality for a cross-premises Exchange deployment scenario.

-PrimarySmtpAddress
This parameter is functional only in on-premises Exchange.
The PrimarySmtpAddress parameter specifies the primary return email address that's used for the recipient.
By default, the primary address is the same as the ExternalEmailAddress parameter value.
If you use the PrimarySmtpAddress parameter to specify the primary email address, the command sets the EmailAddressPolicyEnabled property of the mail user to False, which means the email addresses of the mail user aren't automatically updated by email address policies. We recommend that you don't set the primary email address to a value other than the ExternalEmailAddress unless you're in a cross-forest scenario.
