I have an on-premises ADDC, and I want to sync it with Microsoft Azure Entra ID to utilize Microsoft 365 services. I would like to use Azure Entra ID Connect to synchronize specific users who are members of a group in ADDC so that only those users will be synced to Microsoft Azure Entra ID. Additionally, I have some services like Exchange hosted on-premises, which I have published on the Internet. I want to set up a hybrid Exchange Online for the users who are synced with Azure Entra ID.

My Users use Outlook for their emails.

What is the best practice to address this scenario and converge the on-premises and cloud environments effectively?

    Hi @63470014

    If you are looking to implement a hybrid envirement for Exchange, you should start by synchronise on-premise accounts to Entra ID using Entra connect server or Cloudsync.

    If you want use ENtra ID connect , you should sync OU of target users. Entra ID cannot sync a user based on group membership .

    If you want sync only users membre of a group , in this case you can use Cloud Sync:

    Create a new configuration for Microsoft Entra Cloud Sync

    Regarding the deployment of Exchange hybridation I invite you to read the following article where you will find all details about all requirement configuration:
