Hello Harris,
Good day! Thanks for reaching out. I understand that you're experiencing an issue with polls in Outlook.
To clarify, are you using the built-in poll feature in Outlook or are you using Microsoft Forms to create the poll? The built-in poll feature in Outlook has some limitations, and it might not support restricting users to a single vote. However, Microsoft Forms offers more control over responses. If you’re open to using Microsoft Forms, you can set it up to allow only one response per person by following these steps:
- Go to the Microsoft Forms website and create a new form.
- Add your poll questions and options >Click on the three dots (ellipsis) in the top right corner and select “Settings.”
- Under “Who can fill out this form,” select “Only people in my organization can respond.” >Enable the “One response per person” option.
For the built-in poll feature in Outlook, there isn’t a direct way to restrict users to a single vote. Create a poll in Outlook - Microsoft Support. I'd strongly recommend you submit your valuable feedback directly to the product development team through the outlook app (Help >Suggest a Feature or Give Feedback) or by posting on Outlook · Community (microsoft.com) such that it can be considered for development by the product team.
However, you can consider using Microsoft Forms as an alternative to achieve the desired functionality. Kindly refer to these resources for more information:
Thank you for your time and understanding. For other questions, feel free to add your post to the Microsoft Community.
