I customized the Nintex Workflow CSS File "HTMLEDITORSTYLES.CSS" with the below code and done IIS Reset but i did not find the Font Family Segoe UI in the Rich Text Ribbon and my Changes are not reflected in the Nintex Email Format Text.
Modified the below changes in the htmleditorstyle CSS file
font-family: "Segoe UI", monaco, sans-serif;
Still my Font Family is showing with default CSS Styles as "Calibri" and Font Size to "11pt" to all my Workflow Emails after i modify the CSS Class .ntx-rte-messageBody . I need Font Family as "Segoe UI" and Font Size "10pt" to all my Nintex Workflows. Please Can any one help me out how to resolve my issue.
