Hi,

 

I installed an Exchange 2019 server in an environment running Exchange 2016 hybrid mode. I just realized that Exchange 2019 does not offer free hybrid license, so I want to uninstall it. Is there anyone has experience similar to me? Is there anything I should be aware of after I uninstall the Exchange 2019 server?

 

Please notes that all mailboxes are migrated to O365, the Exchange 2016 server is only using for create new mailbox on O365 and manage them, as my company still use Azure AD Connect.

 

Regards,

Ernest
