Error when adding another account to Teams - User actionable configuration error

Dear @Mark Ollerton,

Based on your description, when attempting to add a second account (@ollerton-commercial.co.uk) to Microsoft Teams alongside your personal Outlook account, Teams displays the error: "Access denied for the resource. User actionable configuration error" (Tag: 4k709). You have tried basic troubleshooting but cannot resolve the issue.

The error "Access denied for the resource. User actionable configuration error" typically indicates that the issue is related to the Microsoft 365 tenant configuration, account permissions, or authentication policies associated with the @ollerton-commercial.co.uk account rather than the Teams client itself.

Here are some suggestions you can try:

1/Verify that the work account can sign in independently

• Sign out of Teams completely.
• Open an InPrivate/Incognito browser session.
• Navigate to Teams on the web and sign in using only the @ollerton-commercial.co.uk account.
• If the sign-in fails, the issue is likely related to the account or tenant configuration.

2/Check Microsoft 365 Licensing

• Confirm that the affected account has a valid Microsoft Teams license assigned.
• Verify that the Teams service is enabled for the user.

3/Review Conditional Access Policies

• Microsoft Entra ID Conditional Access policies may prevent the account from being added to Teams

4/Clear Teams and Cache

• Please follow this article to clear your Teams app cache: Clear the Teams client cache - Microsoft Teams | Microsoft Learn
• Restart the device and attempt to add the account again.

5/Check Tenant Restrictions

• Some organizations block adding managed work accounts to personal Microsoft accounts or other Microsoft 365 tenants.
• The Microsoft 365 administrator for the @ollerton-commercial.co.uk tenant should review Entra ID sign-in logs and account restrictions.

6/ Clear Credentials cache

• Open the Control Panel on your PC.   
• Go to User Accounts > Credential Manager.   
• Under both Windows Credentials and Generic Credentials, look for any entries related to your Microsoft 365 business account and Office apps.   

• Select and remove those entries.   
• Restart your computer and try adding your account in Office again.  

I hope information above can help you resolve the issue, feel free to reach out if you have any other questions.
