<span style="color: rgb(224, 62, 45);">**WARNING:** Once a user has been configured, **it is no longer possible to modify the folder mapping for Contacts, Tasks, and Events**. To change this mapping, manual intervention by technical support is required, including resetting the user's entire configuration. We therefore strongly recommend correctly setting up user folders from the very beginning.</span>
