Microsoft’s Cloud Solution Provider (CSP) uses a CSP portal to access clients’ tenants. This script will fetch the tenant IDs through the CSP credentials. Then it will extract details of all the verified domains within each tenant. Lastly, it will check DKIM, DMARC and SPF txt record details of the tenant’s verified domains and create a get_result.txt file that contains all the details within the same folder.
