Thank you for posting your question in the Microsoft Q&A forum.
Looks like you are referring to this thread. Based on my research, this behavior seems to be related to Outlook reminders automatically taking focus when they appear, which can interrupt the user’s current activity.
Currently, I have not identified any official Microsoft documentation that provides a method to prevent or modify this behavior yet.
If you feel this update would improve the user experience, we would encourage you to submit your feedback directly to Microsoft. You can do so through the Microsoft 365 Feedback Portal. This ensures your inquiry reaches the Microsoft product team, allowing them to better understand user needs, enhance product experience, and potentially prioritize your request in future updates.
Apologies for redirecting you to the appropriate development team. This platform is a user‑to‑user support forum, and moderators, contributors, and external Microsoft employees participating here do not have access to backend systems or the ability to modify product features directly. Our role is limited to offering technical guidance and sharing best practices based on reported issues, feedback, and community discussions.
Please feel free to correct me if I misunderstood your request. If you have any additional concerns, feel free to comment below. I would be more than happy to assist.
