To delete organization items, you must have “Can Manage” permissions to the collection from which you wish to delete items. To check/modify your permissions, log in to the Web Vault, open the Admin Console, click on “Members” in the left-hand navigation menu, then click on your account name in the list of organization members. In the “Edit Member” pop-up, open the “Collections” tab, where you will see what permissions you have for each collection in the organization.
Once you have set your permissions to “Can Manage”, you should be able to delete organization items as usual.
