This question was originally asked on the MSDN Exchange Development forum which focuses on development questions on Exchange.
As the former Outlook forums on TechNet have been migrated to Microsoft Q&A forum, we migrated this question manually in order to continue the discussion here.
Single exchange server organization.
Trying to run the CU19 setup from exchange server and got this error message -
Active Directory must be prepared with 'Setup /PrepareAD'. However, the current user account doesn't have the permissions required even though it's a member of the 'Enterprise Admins' group. Check whether this is a valid user account.

I followed one article (https://supertekboy.com/2017/09/20/error-running-preparead-user-does-not-have-permissions-but-is-a-member-of-enterprise-admins/) and added 'Exchange servers' group to following but that didnt fix my problem.
Computer Configuration > Policies > Windows Settings > Security Settings > Local Policies > User Rights Assignment
Under User Rights Assignments double-click Manage auditing and security log.
I am already member of all the highest priviledge groups like DA, EA, Organization Management but still facing this.
Do i need to run schema command on AD server???
ANY HELP/SUGGESTION IS HIGHLY APPRECIATED, THANK YOU
