Syn AD on Prem with Azure AD

Question

Hello,I have an on-prem environment with AD and Exchange 2016 with domain name mydomain.it and a Tenant mydomain.onmicrosoft.com that I use only for teams now.Users have the same username on-prem and on Azure AD, but with different suffix.&nbsp;My goal is to sync AD with Azure AD and use on-prem Exchange with Teams with mydomain.it.&nbsp;I'm starting with change the username on Azure AD from mailto:email address removed for privacy reasons&nbsp;to mailto:email address removed for privacy reasons&nbsp;and then with Azure AD Connect I sync this user with on-prem and now the user is managed from on-prem.After that I can use Teams with the new address but it is not integrate with Exchange/Outlook, to do that I have to configure an&nbsp;Exchange hybrid deployment.&nbsp;Is that correct?Thank you&nbsp;

Yes, simply matching the UPN will not enable hybrid functionality for Exchange/Teams. Follow the steps here: https://learn.microsoft.com/en-us/microsoftteams/exchange-teams-interact
