Two steps are required to remove a domain from the blocked domains list. First, you must use the New-CsEdgeDomainPattern cmdlet to create a domain object for the domain to be removed:

$x = New-CsEdgeDomainPattern ""

After creating this object, use the following syntax to remove the domain (in this example, the domain stored in the variable $x) from the blocked domains list:

Set-CsTenantFederationConfiguration -BlockedDomains @{Remove=$x}

To remove all the domains from the blocked domains list, set the value of the BlockedDomains property to null ($Null):

Set-CsTenantFederationConfiguration -BlockedDomains $Null
