Hi @Willyams Yujra

This is because your tenant lacks O365 licenses, you need to purchase O365 licenses for your tenants and then assign that license to your users.

Hope this helps.

Hello @Willyams Yujra,

Thanks for reaching out.

Error 401 Unauthorized 'OrganizationFromTenantGuidNotFound' occurs when your Azure AD does not have Office 365 account to work.

If you want to access mailfolders for your development O365 tenant, register the app in your O365 AAD tenant that you got when you created the development tenant.

Please follow the below steps

You need Microsoft 365 account with subscription
In your azure portal login with your Office 365 account
Create app in Azure active directory under App registration and give permissions according to the documentation.
Then use your mailFolders endpoint for users.

Hope this helps.
