Hi, Based on the error messages you've shared, it appears that the issue with your Copilot agent not loading in Microsoft 365 is related to **insufficient permissions or licensing constraints**. Here’s a breakdown of the two key errors and what they typically indicate: --- ### 🔒 Error 1: `403 - notAllowed` / `provisioningNotAllowed` This suggests that the user account attempting to access the agent does **not have permission to create a personal site** (i.e., a OneDrive for Business site). This is often required for Copilot to function properly in Microsoft 365. **Resolution:** - Ensure that the user has a valid **OneDrive for Business license** assigned. - In the Microsoft 365 Admin Center, verify that **personal site creation is enabled** for the user under SharePoint settings. - Navigate to **SharePoint Admin Center > Settings > User Profiles > Manage User Permissions**. - Confirm that the user is allowed to create personal sites. --- ### 🔐 Error 2: `Authorization_RequestDenied` / `Insufficient privileges` This indicates that the user or app does not have the necessary **Graph API permissions** to perform the requested operation. **Resolution:** - If you're using a custom app or bot, ensure that the **Azure AD app registration** has the required delegated or application permissions. - An admin may need to **grant admin consent** for these permissions in Azure Active Directory. - Also, confirm that the user has both: - A **Copilot license** - A **Copilot Studio license** --- ### ✅ Additional Checks - Make sure the agent is **published and shared** correctly in Copilot Studio. - Try accessing the agent from a different browser or in **incognito mode** to rule out caching issues. - If the issue persists, consider checking the **Microsoft 365 Message Center** or **Service Health Dashboard** for any ongoing service disruptions.
