1. Register SBC Domain in Microsoft 365
The SBC domain name must be from one of the names registered in ‘Domains’ of the Enterprise Microsoft 365 tenant. You cannot use the *.onmicrosoft.com tenant for the domain name. For example, the administrator registered the following DNS names for the Microsoft 365 tenant:
|
DNS name |
Can be used
for SBC FQDN |
Examples of FQDN names
|
| brekeke.info | Yes | Valid names:
· test.brekeke.info · sample1.brekeke.info Invalid name: · sbc1.test.brekeke.info (Requires registering domain name test.brekeke.info in ‘Domains’ first) |
| brekeke.onmicrosoft.com | No | Using *.onmicrosoft.com domains is not supported for SBC names |
Log in to the Microsoft 365 Admin center and register your SBC domain under [Settings] > [Domains]. In the screenshot below, “test6.brekeke.com” is registered as an example.
