Hello @MFM
Thank you for reaching out to the Microsoft Q&A forum.
Based on the behavior you described, this aligns with how Scheduling Poll handles organizer access when the poll is created from a generic/shared mailbox instead of a regular user mailbox.
Microsoft states that the organizer is expected to access and manage polls through the organizer dashboard, and the feature is designed around a Microsoft 365 Exchange Online mailbox for the organizer. Microsoft also notes that Scheduling Poll is not supported for shared mailboxes. Because of that, if the poll was created using a generic/shared mailbox, it can cause situations where the account is recognized as the organizer but still cannot properly open the poll results page.
You can review the official references here:
- Scheduling Poll organizer dashboard
- Find the best meeting time for everyone with Outlook Scheduling Poll
- Scheduling Poll voting
What you can try:
- Sign in directly with the same account that originally created the poll.
- Open the organizer dashboard here:
https://outlook.office365.com/findtime/dashboard
- Check whether the poll appears there under Open / Completed polls.
If the poll was created from a shared/generic mailbox, the most reliable workaround is to create future Scheduling Polls from a licensed user mailbox instead of the shared mailbox.
If this poll is business-critical and the results still cannot be accessed, the best next step would be to contact your Microsoft 365 admin/support team so they can review whether the poll ownership is tied to an unsupported mailbox scenario on the service side.
I hope this helps.
