Proabaly being over cautious here but it's one I don't want to do wrong. My Exchange 2007 (migrated from Ex2003) reports thsi error when running the Exchange Best Practice Analyzer: Access control list (ACL) inheritance is blocked for the Exchange Organization object (CN=CHC,CN=Microsoft Exchange,CN=Services,CN=Configuration,DC=CHC,DC=LAN). This may cause mail flow problems, store mounting issues and other service outages. Follow Microsoft Knowledge Base article 264733 and use the Exchange System Manager to re-enable inheritance on this object. I know what needs to be done but am I runnign any risk doing this? Exchange works fine as is.

There are a number of explicit DENY permissions, but I don't have another Ex2007 to check them against to swee if they're the 'norm'. I think the reason inheritance was removed was for GFI MailEssentials as there's an account named 'GFI' added at this level, which couldn't have been unless Inheritance was removed. Are these normal permissions at this level?

Hello healthyCamper, I suggest you go to enable inheritance for permissions on Organization object.

Hi Evan, Will be doing this weekend to allow back-out time just in case. Not in office this week.

Happy to say my paranoia ill-founded. Change made, server restarted and no issues to report plus a nicer looking ExBPA
