The error message suggests that the Business Central (BC) Outlook add-in is unable to locate the correct page. Here are some troubleshooting steps to resolve this:

1. Verify Business Central URL in Outlook Add-in Settings

Open Outlook → Go to Add-ins → Locate the Business Central Add-in.
Check the URL configured inside the add-in. Ensure it matches your BC environment (e.g., https://businesscentral.dynamics.com with the correct tenant and environment).

2. Check User Permissions in Business Central

Ensure your Microsoft Entra ID (Azure AD) user has proper access to Business Central.
Go to BC Admin Center → Users and confirm that your user has the required roles (e.g., D365 Business Central User).

3. Ensure Business Central Web Services Are Enabled

In BC, search for "Web Services" and confirm that required services like OData and SOAP are enabled.

4. Clear Cache & Try Different Browser

Clear your browser cache and cookies.
Try logging into BC via Incognito Mode or a different browser before retrying the add-in.

5. Check Entra ID & OAuth Authentication Issues

Ensure OAuth authentication is configured correctly in BC.
Verify that your Microsoft Entra ID (formerly Azure AD) is linked properly to BC.
If using multi-factor authentication (MFA), try logging in via the Office 365 portal first.

6. Reinstall the Business Central Outlook Add-in

Uninstall the BC Outlook Add-in and re-add it via:
- BC → Assisted Setup → Set Up Business Central Add-in for Outlook
- Outlook → Get Add-ins → Search for Dynamics 365 Business Central

If the issue persists, you may need to check with Microsoft Support by providing the Entra Tenant ID from the error message.
