Use the Set-MailboxJunkEmailConfiguration cmdlet to configure the junk email rule for specific mailboxes.

Syntax

Set-MailboxJunkEmailConfiguration -Identity <MailboxIdParameter> [-BlockedSendersAndDomains <MultiValuedProperty>] [-Confirm [<SwitchParameter>]] [-ContactsTrusted <$true | $false>] [-DomainController <Fqdn>] [-Enabled <$true | $false>] [-IgnoreDefaultScope <SwitchParameter>] [-TrustedListsOnly <$true | $false>] [-TrustedSendersAndDomains <MultiValuedProperty>] [-WhatIf [<SwitchParameter>]]

Examples

EXAMPLE 1

This example disables the junk email rule configuration for the user named David Pelton.

Copy Code
Set-MailboxJunkEmailConfiguration -Identity "David Pelton" -Enabled $false

EXAMPLE 2

This example makes the following configuration changes to the junk email rule for the user named Michele Martin:

  • Adds contoso.com and fabrikam.com as trusted domains.

  • Adds jane@fourthcoffee.com as a blocked sender.

The example uses a temporary variable $Temp to make these changes because the parameters being modified are multivalued parameters. Using a temporary variable preserves any existing values.

Copy Code
$Temp = Get-MailboxJunkEmailConfiguration "Michele Martin"
$Temp.TrustedSendersAndDomains += "contoso.com","fabrikam.com"
$Temp.BlockedSendersAndDomain += "jane@fourthcoffee.com"
Set-MailboxJunkEmailConfiguration -Identity "Michele Martin" -TrustedSendersAndDomains $Temp.TrustedSendersAndDomains -BlockedSendersAndDomains $Temp.BlockedSendersAndDomains

EXAMPLE 3

This example identifies any mailboxes for which the junk email rule is configured to treat contacts as trusted senders and then changes the junk email configuration to not treat contacts as trusted senders.

Copy Code
Get-MailboxJunkEmailConfiguration * | Where {$_.ContactsTrusted -eq $true} | Set-MailboxJunkEmailConfiguration -ContactsTrusted $false

Detailed Description

The junk email rule helps Microsoft Outlook and Outlook Web App users to automatically remove any spam that gets past anti-spam filters and reaches the users' mailboxes. With this cmdlet, users and administrators can make changes to the junk email rule that's configured for a specific mailbox.

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 junk email configuration" entry in the Mail Flow Permissions topic.

Parameters

Parameter Required Type Description

Identity

Required

Microsoft.Exchange.Configuration.Tasks.MailboxIdParameter

The Identity parameter identifies the mailbox.

This parameter accepts the following values:

  • Alias

    Example: JPhillips

  • Canonical DN

    Example: Atlanta.Corp.Contoso.Com/Users/JPhillips

  • Display Name

    Example: Jeff Phillips

  • Distinguished Name (DN)

    Example: CN=JPhillips,CN=Users,DC=Atlanta,DC=Corp,DC=contoso,DC=com

  • Domain\Account

    Example: Atlanta\JPhillips

  • GUID

    Example: fb456636-fe7d-4d58-9d15-5af57d0354c2

  • Immutable ID

    Example: fb456636-fe7d-4d58-9d15-5af57d0354c2@contoso.com

  • Legacy Exchange DN

    Example: /o=Contoso/ou=AdministrativeGroup/cn=Recipients/cn=JPhillips

  • SMTP Address

    Example: Jeff.Phillips@contoso.com

  • User Principal Name

    Example: JPhillips@contoso.com

BlockedSendersAndDomains

Optional

Microsoft.Exchange.Data.MultiValuedProperty

The BlockedSendersAndDomains parameter specifies a list of the individual senders and domains that are blocked by the junk email rule.

Confirm

Optional

System.Management.Automation.SwitchParameter

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.

ContactsTrusted

Optional

System.Boolean

The ContactsTrusted parameter specifies whether the contacts in the Contacts folder are treated as trusted senders. Valid input for this parameter is $true or $false.

DomainController

Optional

Microsoft.Exchange.Data.Fqdn

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

Enabled

Optional

System.Boolean

The Enabled parameter enables or disables the junk email rule on this mailbox. Valid input for this parameter is $true or $false.

IgnoreDefaultScope

Optional

System.Management.Automation.SwitchParameter

The IgnoreDefaultScope parameter instructs the command to ignore the default recipient scope setting for the Exchange Management Shell session and use the entire forest as the scope. This allows the command to access Active Directory objects that aren't currently in the default scope. Using the IgnoreDefaultScope parameter introduces the following restrictions:

  • You can't use the DomainController parameter. The command uses an appropriate global catalog server automatically.

  • You can only use the DN for the Identity parameter. Other forms of identification, such as alias or GUID, aren't accepted.

TrustedListsOnly

Optional

System.Boolean

The TrustedListsOnly parameter specifies that only messages from trusted senders and domains are allowed to be sent to the mailbox. All other messages are considered spam by the junk email rule. Valid input for this parameter is $true or $false.

TrustedSendersAndDomains

Optional

Microsoft.Exchange.Data.MultiValuedProperty

The TrustedSendersAndDomains parameter specifies a list of the individual senders and domains that are considered trusted senders. Messages from these senders and domains aren't processed by the junk email rule.

WhatIf

Optional

System.Management.Automation.SwitchParameter

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.
