Hello Tnicolas51170,
Thanks for your post in Microsoft Community. Coming Soon option IS NOT always available in Outlook. Coming Soon is designed to share significant changes that will soon roll out to Office 365 customers. The Coming Soon button and on/off toggle not be visible once those updates are fully rolled out to production and will appear again only when Microsoft plans to introduce additional, material changes in Outlook for Windows.
Further for “Use tighter spacing button” is available in Outlook 1906 version, so could you please kindly check your outlook version and share us the detail information with screenshot of your Outlook version?
