Settings
The Settings folder has one Outlook item - the settings item in which all the SupportCalls settings data are stored and managed. So, it is highly recommended that you avoid saving any other items in this folder for security and reliability point of view. The technicians' permission on this folder are also needed to be planned out carefully as for every new case, the case count is updated in the settings item, which means, without an adequate permission (editor) on this folder, most likely you will simply get a friendly error message about the failure of the activity you requested for (such as logging in a new case).
