I'm trying to use Powerpoint Live in a Teams meeting with no luck.

To use PowerPoint Live in a Teams meeting, ensure that you meet the following prerequisites:

1. PowerPoint File: Make sure your PowerPoint presentation is saved in OneDrive for Business or SharePoint. Since you mentioned that your PowerPoint is saved on OneDrive, this should be fine.
2. User Token: The app must be able to obtain a valid user token for the OneDrive resource. This is typically handled automatically when you are signed in with your Microsoft 365 account.
3. Supported File Types: Ensure that your PowerPoint file is in a supported format (e.g., .pptx, .ppsx, .potx, .pptm, .ppsm).
4. Meeting Policy: Check that your meeting policy allows sharing PowerPoint presentations. This is a per-user policy, so if your account has restrictions, you may need to adjust those settings or contact your administrator.

If you have confirmed all of the above and still do not see the option to use PowerPoint Live, try the following steps:

• Restart Microsoft Teams and try again.
• Ensure that you are using the latest version of Teams.
• Check if the feature is enabled in your Teams settings or consult with your IT administrator if you are part of an organization.

If everything is set up correctly, you should be able to share your PowerPoint presentation using PowerPoint Live and access links for your audience directly from your shared presentation.
