How do I add the $i parameter as a new property? - powershell

Question

How do I add the value of $i as a new parameter to the object so that if $i is part of distinguishedName?
param([string[]]$Country="Norway,Denmark")
foreach ($i in $Country)
{
$users += Get-ADUser -searchbase "ou=$i,ou=FMS,dc=ce,dc=xxxx,dc=net" -ldapfilter $ldapfilter -properties CN,SamAccountName,mail,title,department,company,pager,employeeNumber,distinguishedName,extensionAttribute12
$users | Add-Member -MemberType NoteProperty -Name "OOU" -Force -Value ""
{missing code to add $i as value for property .OOU}
}
$users | Add-Member -MemberType NoteProperty -Name "license" -Force -Value ""
$users | where extensionAttribute12 -Like "*EOP1*" | %{$_.license="EOP1"}
$users | where extensionAttribute12 -Like "*E1*" | %{$_.license="E1"}
$users | where extensionAttribute12 -Like "*E3*" | %{$_.license="E3"}
I have tried to do the same as with the where clause in the bottom part, but the foreach loop makes it overwrite all values with the last member of $i

Use the -Value parameter to specify the initial value of a new property:
$users | Add-Member -MemberType NoteProperty -Name "OOU" -Force -Value $i
To avoid re-assigning the newest values to all the existing users that have already received their new OOP property, use an intermediary variable to hold the output from Get-ADUser:
foreach ($i in $Country)
{
$country_users = Get-ADUser -searchbase "ou=$i,ou=FMS,dc=ce,dc=xxxx,dc=net" -ldapfilter $ldapfilter -properties CN,SamAccountName,mail,title,department,company,pager,employeeNumber,distinguishedName,extensionAttribute12
$users += #($country_users | Add-Member -MemberType NoteProperty -Name "OOU" -Force -Value $i)
}
