Skype add-in gets disabled every time logging to teams

Hossam_RIAD 

I've written a small PowerShell script that adds DENY SetValue for the current user to this registry key's ACLs. After running it, Teams (running in user context) won't be able to change the value and it'll persistently remain at 3 (enabled in Outlook). Feel free to try, modify for the IMProvider key, and distribute. 

$regPath = 'Registry::HKCU\Software\Microsoft\Office\Outlook\Addins\UCAddin.LyncAddin.1'

Set-ItemProperty $regPath -Name LoadBehavior -Value 3

$acl = Get-Acl $regPath
$acl.Access | FT *

$idRef = [System.Security.Principal.NTAccount]([System.Security.Principal.WindowsIdentity]::GetCurrent().Name)
$regRights = [System.Security.AccessControl.RegistryRights]::SetValue
$inhFlags = [System.Security.AccessControl.InheritanceFlags]::None
$prFlags = [System.Security.AccessControl.PropagationFlags]::None
$acType = [System.Security.AccessControl.AccessControlType]::Deny

$rule = New-Object System.Security.AccessControl.RegistryAccessRule ($idRef, $regRights, $inhFlags, $prFlags, $acType)

$acl.AddAccessRule($rule)

$acl | Set-Acl -Path $regPath

$acl = Get-Acl $regPath
$acl.Access | FT *
