Microsoft Outlook for Windows and web will release 10 new themes in addition to the existing 55 themes. Users can access these themes in the Appearance page of Settings. The release will begin in early March 2024 and complete by late March 2024. Users within the tenant will have 10 new options when selecting themes. If the organization wants to prevent users from accessing these new themes, they can disable them and set their own theme in the Microsoft 365 admin center.
