If you are using Entra ID Connect (aka Azure AD Connect), you may already know about the existence of the group writeback functionality (https://learn.microsoft.com/en-us/entra/identity/hybrid/connect/how-to-connect-group-writeback-v2/) which allows you to provision groups on your Active Directory from Entra ID.
Well, you need to get ready for the group writeback depreciation starting June 30, 2024.
Group writeback is being replace with the new Group Provision to AD feature (see https://learn.microsoft.com/en-us/entra/identity/hybrid/cloud-sync/how-to-configure-entra-to-active-directory/)
