To share more knowledge 🙂

$webRequest = [Net.WebRequest]::Create("https://www.outlook.com")
try { $webRequest.GetResponse() } catch {}

$bytes = $cert.Export([Security.Cryptography.X509Certificates.X509ContentType]::Cert)
set-content -value $bytes -encoding byte -path "$pwd\Outlook.Com.cer"

My co-worker Michael J. Lyons shared this with me.
