Hybrid exchange and shared mailboxes on-prem
OK, the 2016 Hybrid licence key is provided by Microsoft on the provision that you do not host any mailboxes on that 2016 hybrid server. If you were to host any mailboxes on that server, then you would need to acquire an Exchange 2016 licence.
Are you just using Exchange 2016 as the hybrid server? Do you have other Exchange 2010 or 2013 servers in your environment? If so, then shared mailboxes may be hosted on those servers no problem in a hybrid coexistence.
I always recommend migrating any shared mailboxes to Exchange Online alongside any logical groups of user mailboxes that you are migrating to the cloud. Best to keep groups and teams in the same environment where possible as it works much better.
