Remove-IPBlockListEntry

 

Applies to: Exchange Server 2016

This cmdlet is available or effective only on Edge Transport servers in on-premises Exchange Server 2016.

Use the Remove-IPBlockListEntry cmdlet to remove IP block list entries that are used by the Connection Filtering agent on Edge Transport servers.

Remove-IPBlocklistEntry -Identity <IPListEntryIdentity> [-Confirm [<SwitchParameter>]] [-Server <ServerIdParameter>] [-WhatIf [<SwitchParameter>]]

This example removes the IP address 192.168.0.100 from the IP Block list.

Get-IPBlockListEntry | Where {$_.IPRange -eq '192.168.0.100'} | Remove-IPBlockListEntry

This example removes the IP address range 192.168.0.0/24 from the IP Block list.

Get-IPBlockListEntry | Where {$_.IPRange -eq '192.168.0.0/24'} | Remove-IPBlockListEntry

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 "Anti-spam features - Edge Transport" entry in the Anti-spam and anti-malware permissions topic.

 

Parameter Required Type Description

Identity

Required

Microsoft.Exchange.Configuration.Tasks.IPListEntryIdentity

The Identity parameter specifies the integer value of the IP Block list entry that you want to remove. When you add an entry to the IP Block list, the Identity value is automatically assigned. To find the Identity value of an IP Block list entry, use the Get-IPBlockListEntry cmdlet.

Confirm

Optional

System.Management.Automation.SwitchParameter

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.

Server

Optional

Microsoft.Exchange.Configuration.Tasks.ServerIdParameter

The Server parameter specifies the Exchange server where you want to run this command. You can use any value that uniquely identifies the server. For example:

  • Name

  • FQDN

  • Distinguished name (DN)

  • Exchange Legacy DN

If you don't use this parameter, the command is run on the local server.

You can't use this command to configure other Edge Transport servers remotely.

WhatIf

Optional

System.Management.Automation.SwitchParameter

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.
