Detailed Description

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 "Mailbox permissions and delegation" entry in the Mailbox Permissions topic.

Parameters

Parameter Required Type Description

Identity

Required

Microsoft.Exchange.Configuration.Tasks.MailboxIdParameter

The Identity parameter identifies the mailbox. You can use one of the following values:

  • GUID

  • ADObjectID

  • Distinguished name (DN)

  • Domain\Account

  • User principal name (UPN)

  • LegacyExchangeDN

  • SmtpAddress

  • Alias

Credential

Optional

System.Management.Automation.PSCredential

The Credential parameter specifies the user name and password to use to access Active Directory.

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.

DomainController

Optional

Microsoft.Exchange.Data.Fqdn

The DomainController parameter specifies the fully qualified domain name (FQDN) of the domain controller that retrieves data from Active Directory.

Owner

Optional

System.Management.Automation.SwitchParameter

The Owner parameter returns the owner information for the mailbox identified in the Identity parameter.

This parameter can't be used with the User parameter.

ReadFromDomainController

Optional

System.Management.Automation.SwitchParameter

The ReadFromDomainController parameter specifies that the user information is read from a domain controller in the user's domain.

If you set the recipient scope to include all recipients in the forest, and if you don't use this parameter, it's possible that the user information is read from a global catalog with outdated information.

If you use this parameter, multiple reads might be necessary to get the information.

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

ResultSize

Optional

Microsoft.Exchange.Data.Unlimited

The ResultSize parameter specifies the maximum number of recipient objects returned.

User

Optional

Microsoft.Exchange.Configuration.Tasks.SecurityPrincipalIdParameter

The User parameter specifies the UPN, domain\user, or the alias of the user.
