Hi @Zitok, Chen,
Thank you very much for taking the time to share your question with us in the Microsoft Q&A forum.
Based on your description, it looks like the challenge you’re facing is closely tied to a Microsoft Power Automate (Flow) scenario, particularly around design logic and licensing behavior rather than a core Microsoft 365 feature.
As this forum category mainly focuses on Microsoft 365 and Office products, our coverage and hands‑on expertise with Power Automate‑specific configurations, connectors, and licensing considerations are unfortunately quite limited. To make sure you receive the most accurate, in‑depth guidance and to avoid the risk of giving you incomplete or misleading information, I’d recommend posting your question in the Microsoft Power Platform Community instead.
This community is dedicated to Power Automate and related services, and it’s actively supported by specialists and experienced partners who work with these scenarios on a regular basis. There, you’ll be able to connect with contributors who have practical experience with Planner connectors, Azure AD user resolution, licensing constraints, and alternative notification approaches that go beyond channel‑based messaging.
I truly apologize for redirecting you to a different community, and I sincerely appreciate your understanding. My goal is simply to help you get the best and fastest possible support by guiding you to the forum that’s best equipped to assist with your specific use case.
Thank you again for your patience and cooperation. I wish you the very best of luck with refining your flow design, and I hope you’ll find the detailed assistance you’re looking for soon.
