Hello @AnushkaKa1
Thanks for posting here.
To hide the Profiles folder under Customer Management for a specific user in the Adobe Campaign Classic v8 Web UI, you must configure folder-level security settings. Permissions are managed at the operator group level, not for individual operators.
1. In the Campaign Explorer (via the desktop client), navigate to Administration > Access management > Operator groups.
2. Right-click the list and select New.
Enter a descriptive name for the group, such as "Marketing No Profiles".
3.Define the appropriate named rights for this group, making sure not to include any rights that grant broad access to recipient data.
4. Save the new operator group.
