Register Customer Tenant Sub domain

The registration of the customer Subdomain is performed in the Customer Microsoft 365 admin center and in the Service Provider tenant DNS Zone:

■

The customer must generate a TXT record to validate with the Service Provider domain and an A-record to translate the customer site SBC shortname (configured in the Onboarding wizard) to its IP address and FQDN.

■

The Service Provider must add the new record in the DNS Zone.

➢
