Using classic Outlook for Windows in business environments
Hello @Wong Suet Ling
If the Polls option is missing or you can't insert a poll in Outlook, I would first check whether the Microsoft Forms/Polls integration is available for your account.
A few things to check:
• Try New Outlook on the web and create a new message. See whether Apps / Polls is available there.
• If Polls is missing, your organization's Microsoft 365 administrator may have disabled the Polls/Forms app or restricted Office add-ins.
• Sign out and back in, then try Outlook on the web rather than the desktop client. This helps determine whether it is a client-specific issue.
• If the Polls option appears but fails when you use it, check whether Microsoft Forms is working normally for your account.
If this is a work/school account, your Microsoft 365 admin should also check the organization's app/add-in permissions and Forms licensing/service availability.
If you can share whether you're using New Outlook, Classic Outlook, or Outlook on the web, and whether the Polls button is missing or gives an error, that would narrow it down.
