  4. Thanks for the list.

    For Peoples info, if you have not and don’t want to migrate the public folder database to the new exchange 13/16. You will need to remove it before uninstalling. The easiest way to do this is using ADSI edit to delete the database and then just running the uninstall. Ex2007 & 10 have different locations for the database in ADSI Config just google it.
