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 "Anti-spam features" entry in the Anti-Spam and Anti-Malware Permissions topic.


Parameter Required Type Description




The IPAddress parameter specifies a single IP address to add to the IP Allow list, for example,




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

  • CIDR IP: You can use Classless InterDomain Routing (CIDR), for example,

  • IP range: You can use an IP address range, for example,




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".




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.




The ExpirationTime parameter specifies a day and time when the IP Allow 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 defined in the Regional Options settings for the computer on which the command is run. For example, if the computer is configured to use the short date format mm/dd/yyyy, enter 03/01/2010 to specify March 1, 2010. 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, you must enclose the argument in quotation marks ("), for example, "10/05/2010 5:00 PM".




The Server parameter specifies the Exchange server on which 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 the Server parameter, the command is run on the local server.

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




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.
