Hello, I have a co-existence enviroment with one Exchange 2003 server and one Exchange 2007 server. I am having lots ofActive Directory permission issues since the installation of Exchange 2007. Things like Server permission and Exchange group permissions to objects in Active Directory. Can I re-run the following commands on a production enviroment to get the Active Directory permissions reset to default values? setup /PrepareLegacyExchangePermissions setup /PrepareSchema setup /PrepareAD [/OrganizationName: <organization name> ] setup /PrepareAllDomains Thanks

Hello, Yes it is a safe game re-running Prepare* commands in production environment. These commands correct the predefined things of Exchange references in AD if something is corrupted or missing. How to Prepare Active Directory and Domains http://technet.microsoft.com/en-us/library/bb125224.aspx
