Replacing attributes without removing

Hello everybody, i’m having an issue with one of my script for Active directory administration.

I want to replace something in Extensionattribute10, i’m starting with something like this:

 

Extensionattribute10: Office365licenceE1,anotherlicence

I want to only change the office licence and get

Extensionattribute10: Office365licenceE3,anotherlicence

And i need to keep everything as is after the office licence

 

here is what i got for now:

[pre]

Function E1toE3 {
foreach($user in $global:users){
$e3 = “E3 license”
$script:ADUserint = Get-ADUser -identity $user -server ****** -properties extensionAttribute10
$OldAttr10 = $script:ADuserint.extensionAttribute10
if($oldAttr10 -like “E1 License”){
Set-ADUser -credential $cred -server ****** -identity $user -Replace @{extensionattribute10=“E1 license”}
$NewAttri10 = Get-ADUser -identity $user -server “******” -properties extensionAttribute10
set-Aduser $aduserint.samaccountname -cred $cred -Server ****** -replace @{“extensionattribute10” = $newtattri10+$e3}
Write-host "`n E1 remplacé par E3 sur le compte de $user "-BackgroundColor black -ForegroundColor green
Write-host “”
pause
}
elseif($oldAttr10 -ne “E1 license”) {
write-host “`nChoix invalide, l’utilisateur n’a pas d’e1” -BackgroundColor red -ForegroundColor white
pause
}
}
}

[/pre]

 

The problem is, i just end up with :

 

Extensionattribute10: Office365licenceE3

everything else is removed.

Can someone throw me an idea?

i found a way, putting it here if anyone ever needs a solution

 

[pre]

foreach($user in $global:users){
[string]$script:ADUserint = Get-ADUser -identity $user -properties extensionAttribute10 | select extensionattribute10
}

$script:ADUserint| foreach {
$items = $_.split(",")
}
set-Aduser $user -cred $cred -replace @{“extensionattribute10” = “license,”+$items[1]}
Get-ADUser $global:users -properties extensionAttribute10

[/pre]
