I'm sure you've all heard since the announcement at Ignite that there will be no Standard Edition of Skype for Business 2019. Enterprise deployments will be the only option. I keep hearing clients and others grumble about this, so I went ahead and added it as a feedback item to SkypeFeedback.com. If you feel strongly about this existing as a platform, please sign in and vote, and comment your business case if you wish too.
