Just installed an on-premises AD forest to join with our Azure AD. I setup AD connect for synchronization. I want to sync down the accounts from Azure AD into my new on-premises AD forest (which is brand new and empty). I only see instructions for pushing on-premises account up, but nothing about pulling them down. Any ideas what I'm missing?
you didn't miss anything, Azure AD Connect only syncs user accounts from your on premises AD to your Azure AD. https://azure.microsoft.com/en-us/documentation/articles/active-directory-aadconnect/
