Allow CSP admin (delegated administrator) to manage SharePoint site collections
Being MIcrosoft's Cloud Solution Provider (CSP), I have to manage users, groups and permissions of Site Collections in my customer’s tenant using PowerShell/CSOM as CSP administrator (delegated administrator).
The requirement is, I cannot use credentials of global admin and Site Collection admin to perform above mentioned tasks. The only credentials I have are of CSP Admin (delegated admin).
Although, there is an option to add support partner "Add Support Partner" (Foreign principal for "Company" in Role "TenantAdmins" (Global Microsoft Support Tenant Contract)) in SharePoitn Online admin portal . But there is no API or PowerShell commands to add support partner for automation.
It would be good if Microsoft provides API or PowerShell commands to add support partner for site collections. Or the other way around is to grant "Site Collection administrator"permissions to CSP admin by default.
