Required Parameters

-IPAddress

The IPAddress parameter specifies a single IP address to add to the IP Block list, for example, 192.168.0.1.

Type:IPAddress
Position:Named
Default value:None
Accept pipeline input:False
Accept wildcard characters:False
Applies to:Exchange Server 2010, Exchange Server 2013, Exchange Server 2016
-IPRange

The IPRange parameter specifies a range of IP addresses to add to the IP Block list. You can use the following formats:

  • CIDR IP:192.168.0.1/24

  • IP address range:192.168.0.1-192.168.0.254.

Type:IPRange
Position:Named
Default value:None
Accept pipeline input:False
Accept wildcard characters:False
Applies to:Exchange Server 2010, Exchange Server 2013, Exchange Server 2016

Optional Parameters

-Comment

The Comment parameter specifies an optional comment. If you specify a value that contains spaces, enclose the value in quotation marks ("), for example: "This is an admin note".

Type:String
Position:Named
Default value:None
Accept pipeline input:False
Accept wildcard characters:False
Applies to:Exchange Server 2010, Exchange Server 2013, Exchange Server 2016
-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.

Type:SwitchParameter
Aliases:cf
Position:Named
Default value:None
Accept pipeline input:False
Accept wildcard characters:False
Applies to:Exchange Server 2010, Exchange Server 2013, Exchange Server 2016
-ExpirationTime

The ExpirationTime parameter specifies a day and time when the IP Block list entry that you're creating will expire. If you specify a time only and you don't specify a date, the current day is assumed.

Use the short date format that's defined in the Regional Options settings on the computer where you're running the command. For example, if the computer is configured to use the short date format mm/dd/yyyy, enter 09/01/2015 to specify September 1, 2015. You can enter the date only, or you can enter the date and time of day. If you enter the date and time of day, enclose the value in quotation marks ("), for example, "09/01/2015 5:00 PM".

Type:DateTime
Position:Named
Default value:None
Accept pipeline input:False
Accept wildcard characters:False
Applies to:Exchange Server 2010, Exchange Server 2013, Exchange Server 2016
-Server

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 parameter to configure other Edge Transport servers remotely.

Type:ServerIdParameter
Position:Named
Default value:None
Accept pipeline input:False
Accept wildcard characters:False
Applies to:Exchange Server 2010, Exchange Server 2013, Exchange Server 2016
-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.

Type:SwitchParameter
Aliases:wi
Position:Named
Default value:None
Accept pipeline input:False
Accept wildcard characters:False
Applies to:Exchange Server 2010, Exchange Server 2013, Exchange Server 2016
