Yes, you can configure a Conditional Access policy to allow users in a specific group to upload files to a particular website while blocking others. In the Microsoft Entra admin center, you can create a conditional access policy that targets the users and groups you want to apply the policy to, and then specify the allowed and blocked websites under the policy settings.
To implement this:
- Sign in to the Microsoft Entra admin center.
- Navigate to Identity > Protection > Conditional Access.
- Create a new policy and name it.
- Select the users and groups that you want to apply the policy to.
- Set the Target resources to include the specific website you want to allow.
- Under Session, you can configure the settings to block uploads to the other websites you want to restrict.
This way, you can effectively manage which websites users can upload documents to based on your organization's requirements.
