Before you begin
If you have problems displaying emojis on Windows, upgrade Windows 10 to the latest release to ensure you have Segoe UI Emoji font 1.12 or a later version.
When you're composing a message, type an emoticon leaving a space after the text, and Webex will automatically change it to an emoji. By the way, you can still add emojis to your messages or use emoji shortcodes like you always have.
Take a look at some of the more common emoticons, and their equivalent Windows and Mac emoji characters. There are many more - just include emoticons in your messages and see them change to emoji.
