In Agentforce Sales (formerly Sales Cloud) and Agentforce Service (formerly Service Cloud), Chatter allows users to collaborate through posts and comments. When you enter more than 10,000 characters in a Chatter post or comment, Salesforce displays the error: "Your post is too long." This character limit includes both visible text and formatting tags in rich-content posts meaning HTML tags added by the editor count toward the 10,000-character total even though they are not visible to the reader.
