With the schema extended, the next step is to add all of the containers, objects, attributes, and other items that Exchange uses to store information in Active Directory. Most of the changes made in this step are applied to the entire Active Directory forest. A smaller set of changes are made only to the local Active Directory domain where the /PrepareAD command was run (or where the first Exchange server was installed using the Exchange Setup wizard).

That is what our team is exactly looking, on what pieces of containers, objects, attributes is getting added here or getting changed or getting updated.

- AnnTaeYounJul 19, 2024MVPThe primary reason for running the /PrepareAD command is to prepare Active Directory (AD) for Exchange Server deployment.
Therefore, if there are no updates to the schema, there will be no changes to additional objects through /PrepareAD.
The following links provide details on schema changes.

From what i understand, when we install Exchange, the first thing what Exchange does is it will create a list of containers and objects in AD, that got us thinking about the below listed questions:
What all AD Objects, groups, containers will be touched/modified which needs Enterprise Admin Rights beyond the "FullAccess" rights which we already have on the Exchange Org container
We noticed that the Setup file was trying to access "Audit Security Privilege" on the Domain Controllers, why and what changes it's trying to make in CU14
Any other changes, where /PrepareAD will touch the objects out of the Exchange Org container, if yes please share those, and what changes/modifications it's going to make to them and why- PoorMens_BravoJul 19, 2024Brass ContributorTo add, this CU is doing some global updates which will require an Enterprise Admin account, we saw some Audit Security Policy logs in our DCs and hence this is touching something outside the Exchange container of which the Exchange accounts do not have permissions to do the job.
