Hello SureshNarne 

Welcome to the Microsoft community, my name is Recep I'll be happy to help you today.

Conditional Access policies in Microsoft Intune allow you to control access to applications based on conditions such as device compliance, location, and user groups.

1. Create a Conditional Access Policy:-

• Go to the Azure portal.
• Navigate to Azure Active Directory > Security > Conditional Access.
• Create a new policy.
• Specify the conditions under which access should be granted or denied.

Limiting Access to YouTube:

• You can set conditions based on applications. However, keep in mind that directly restricting access to YouTube might be challenging. You may need additional solutions or services for more granular control.

1.  App Protection Policies:

App Protection policies in Intune can help protect company data accessed by apps, but it might not provide the granularity needed for restricting specific personal email access.

App Protection Policies:

Define policies to protect data within apps.

For example, you can restrict copy-paste operations between corporate and personal apps, but direct blocking of personal email access might not be available.
