This feature is available on Premier and Master editions
This could be a result of the MSS user previously being classified as a company level user with Org Unit Permissions defined.
To verify and correct:
Step 1: Change the user type from Employee to Company.
Navigate > Config > Security > Security > User Profiles
Step 2: Locate the MSS User's email address on the User Org Unit Permissions screen and switch on the "allow access to all employees" toggle.
Navigate > Config > Security > Security > User Org. Unit Permissions
Step 3: Change the user type from Company level back to Employee level on the User Profile screen.
Navigate > Config > Security > Security > User Profiles
