Hi @MichaelRBeetley,
Welcome to Microsoft Q&A, and thank you very much for reaching out.
Based on your description, unfortunately as Q&A assist mentioned, there is no supported option to disable email reactions in Outlook currently, whether on mobile (Android/iOS) or on desktop. As a forum moderator, I’m unable to make changes to product features and can only share information based on publicly available documentation and resources.
That said, I did find an existing Microsoft Feedback requesting this same capability. I recommend reviewing it and adding your vote or comment. The more feedback Microsoft receives on this request, the more likely it is to be considered for future updates.
Thank you for your understanding.
