How to determine if I'm using Oauth On prem Exchange hybrid / Skype for business

Question

Hi Guys , Hope someone can answer me this question or provide some feedback I was ask to look at something today regarding and issue we having with 3rd parity outook add-in and our Exchange 2016 CU16 on-prem environment . As apart of this I discovered that our Exchange Auth Certification was missing from cert list . Started to investigate further and it looks like if was expired earlier this year .

So I started to look at the process of creating a new one . This link from my prospected look like a good how to (if there a better one I love to see )
https://www.messaginginsight.com/2017/06/03/setting-or-renewing-a-new-exchange-auth-certificate/

But one section stood out to me ... "The process for creating a new Server Auth certificate is simple and generally does not cause issues for Exchange UNLESS you are integrated in a hybrid Office 365 environment, or have integration with Sharepoint or Lync that utilizes OAuth. We have a 0365 Hybrid and skype for business but I can not recall setup Oauth . How does one determine if my exchange environment is setup for it and does my hybrid or SKYBE is using OAutrh ... All I can find is this exchange command

Get-OrganizationConfig | Format-Table Name,OAuth* -Auto

The output is

Name OAuth2ClientProfileEnabled ---- --------------------------
MyORG False
This output is implying that is not enabled on Prem . thus isn't a factor with my Hybrid connector and skype for business setups If this isn't .... How does one determine this Thanks Dean

@Dean Maher ,

You can get the information about the OAuth configuration settings currently in use in your organization by the following command:
Get-CsOAuthConfiguration
