Create and display a custom logon message to be displayed on the Log On page.
Your message can be written in plain text, or formatted using HTML. If you create an HTML formatted message, you are responsible for all formatting and escaping.
Custom logon messages with HTML are now escaped by default to prevent Cross-site Scripting (XSS) issues. To include HTML markups and prevent formatting issues, go to the <ePO_install_location>\Server\conf\orion folder, open the orion.properties file, add secure.login.custom.message=false, and save the file and restart ePO - On-prem services.
Select Menu → Configuration → Server Settings, select Logon Message from the Setting Categories, then click Edit.
Select Display custom logon message, then type your message and click Save.
