Dear Kang Yanyi,
Good day! Thank you for posting to Microsoft Community. We are happy to help you.
As per your description, it seems that you have inserted a Poll in Outlook, and need to retrieve the detailed results or when will the data submitted.
If the understand above is right, based on our test and search, we found that Polls created in Outlook are Forms that set to" Anyone can respond". We'd recommend you access https://forms.office.com/ to see detailed responses by clicking on Open in Excel as shown below:
For your reference: Create a poll in Outlook - Microsoft Support
Hope the above information can help.
If the scenario above is not consistent with yours, you can also post back and point that.
Your patience and understanding are highly appreciated. We hope that you are keeping safe and well!
Sincerely,
Rhoda | Microsoft Community Moderator
