Hi @Deni Garo

What is your Skype for Business DNS records?

In my experience, every Office 365 customer needs to add two records to their external DNS. The first CNAME record ensures that Office 365 can direct workstations to authenticate with the appropriate identity platform. The second required record is to prove you own your domain name. For more details, you can refer to:
