AD Hybrid MailUser

I started a new job and noticed that the Exchange Online but the AD is hybrid and all the exchange attributes need to be managed in on-premises AD for proxyAddresses and Aliases. I didn't see an Exchange Server and was told it was uninstalled. How would I check that? 

I need to create a few MailUsers but the user accounts already exist. I have read that I should be able to Enable-Mailuser but that doesn't exist on Exchange online. 
How should I proceed in converting some Users to MailUsers without an exchange server on premise?
