We dont use Azure for anything. Never had and dont plan to do so anytime soon. But we did purchase an Office 365 Business Essentials subscription so we could try out Teams for a small group of users. When we did that, Microsoft gave us the ability to synchronize our Active Directory accounts from on-prem Domain Controllers to Azure AD via Azure AD Connect. This has worked well, but we plan to discontinue use of Teams and Office 365. I would like to keep the Azure AD Connect option/service though as it allows us to use our AD accounts as Microsoft accounts. if we dont have Office 365 anymore, do we lose that service? If so, how do we get it back without having Office 365? And are there tiers of services that we can choose from?
