Hi @Y.W
Welcome to Microsoft Q&A forum
I understand you are facing the issue with "create planner task" option missing when you hover over a Microsoft Teams message
To better understand, may I clarify:
1.Does the 'Create Planner Task' option disappear for all messages, or only for messages from external users (people outside your organization)?
2.Are you using the Teams desktop app, mobile app, or web version? If it’s the desktop or mobile app, please ensure you are in the latest version.
3.Can you still access the Planner app directly at planner.cloud.microsoft/webui?logout=1, and are tasks syncing correctly there? If not, is there any error message when you attempt to access?
As the first step, I recommend checking your Microsoft 365 permissions and licensing:
-Sign in to My account with your Microsoft 365 credentials.
-Look for the "Subscriptions" section to see your assigned plan
-Check if Microsoft Planner is listed as an included service.
If you have difficulty accessing this information or don’t see Planner in your subscription, please contact your IT admin and ask them to verify your license and permissions in the Microsoft 365 Admin Center
Note: If you’re unsure who the IT Admin is within your organization, you can find guidance on locating them here: How do I find my Microsoft 365 admin? - Microsoft Support.
If you are certain, you have a Microsoft Planner license, you can try the following steps:
1.Go to the left tab of teams and click on the 3 dots search workflows.
2,Go to workflows, select create, find "create a planner task from a message", select that section -> Choose Next.
3.Set up your flow -> Create flow.
Once you have successfully set up the flow, you will receive the message "Your flow is ready to run!" Then, you can check if the "Create Planner Task" option appears
The initial response may not fully address your needs, but it will help me better understand your situation. Once I get the information, I will try my best to find the next steps
