Note Office 365 Small Business customers who have custom verified domains have those domains fully redelegated to Office 365. "Full domain redelegation" indicates a domain for which the name server (NS) resource records point to Office 365. Therefore, the Domain Name System (DNS) records that are required for Office 365 functionality are managed by Office 365.

- Click the Office 365 tab.
- Under Microsoft Lync Tests, click Office 365 Lync DNS Test, and then click Next.
- Enter the address that you use to try to sign in to Skype for Business Online (for example, firstname.lastname@example.org), and then start the test.
