The document viewer is automatically available for all users. When you want to exclude certain user groups you can use the Grouping and Filtering functionality in SuperOffice Admin. Make sure you uncheck those groups you want to exclude.

• Click on the hamburger icon and choose Settings and Maintenance.

• Go to Lists - Gui Web panel.
• See if Grouping and Filtering is on.

• If this is on select the Document Viewer panel.
• See if the correct user groups are checked. If not, please turn this off for those groups you want to exclude.
