Check the updated Email Client Compose Email 6. To customize the functions available on the Editor toolbar, you need to edit the "glide.ui.html.editor.v4.toolbar.line1" property. By design and default, the editor on the Email Client form looks to the global settings of the toolbar and cannot be edited separately (as opposed to editors on specific tables). Please keep this in mind when making changes to the property as it can affect the functions available elsewhere. For a list of functions that can be added, please refer to our documentation here: https://docs.servicenow.com/bundle/tokyo-platform-administration/page/administer/form-administration/task/t_ConfigureTheTinyMCEHTMLToolbar.html **Note: the documentation may change over time. Please search the Docs site for keyword 'glide.ui.html.editor.v4.toolbar.line1' if the link does not work.
