changing a users pst /ost file size remotely powershell

Does anyone have a powershell script that will remotely change a users .ost file size in the registry remotely


HKEY_CURRENT_USER\Software\Policies\Microsoft\Office\15.0\Outlook\PST

I want to change these two values MaxLargeFfileSize and WarnLargeFileSize to a certain value

I found this below but not sure how to setup this to work with the command below.


/$reg = [Microsoft.Win32.RegistryKey]::OpenRemoteBaseKey('LocalMachine', $computername )
        $regKey= $reg.OpenSubKey("SOFTWARE\\Microsoft\\Windows\\CurrentVersion\\Run",$true)
        $regKey.SetValue("New_Valuename_String","New_Valuedata",[Microsoft.Win32.RegistryValueKind]::String)
