This article describes a permissions issue experienced with Outlook 2007. Outlook clients were unable to view messages when in on-line mode, with the following error displayed: "Cannot display the folder. You do not have sufficient permission to perform this operation on this object. See the folder contact or your system administrator." The error was related to permissions on the Exchange Organization object in Active Directory. Permissions assigned to the Everyone group had been removed. Restoring the permissions to the defaul resolved the issue. The article describes how the problem was identified and the resolution steps required.
