Back in July, Microsoft announced its new emoji system which included 1800+ emojis redesigned based on Fluent Design. These new emojis are already available on Windows. Today, Microsoft has confirmed that the new Fluent Design-based emojis are coming to Microsoft Teams in November.
Teams is joining M365 and Windows in updating all emojis and reactions to the new Microsoft Fluent emoji style, bringing users a more vibrant and expressive emoji experience.
