In Dynamics CRM, settings like default currency, number of records per page of view, and email tracking options are stored in the MSCRM database as user settings. This means that a user manages these settings. There are supported ways of updating these settings via the SDK, but Microsoft does not provide a UI for administrators to change these settings for all users.
Tanguy Touzard has recently added a tool to his amazing XRM Toolbox called “User Settings Manager” that allows a System Administrator to easily manage and update user settings for all users.
I can select one or more users, update the setting on the right, then hit “Update user settings” to apply the settings. Now that I can control user settings and sync filters globally, the XRM toolbox is my go-to tool for CRM user administration.
