Symptoms
Office 365 and Azure subdomain form from KB#128486 shows a false positive result, e.g. a check for "contoso.onmicrosoft.com" is successful despite the fact that that domain is already occupied.
Network tab in browser debugger console shows a request to Yahoo that contains the warning:
html table is no longer supported.
Note: it may affect any version of OSA since it is related to the subdomain form which is part of O365/Azure APS package.
Cause
Yahoo recently changed their APIs, so the original mechanism used by sudomain form no longer works.
The issue will get permanently addressed in scope of request with internal ID APSA-18370.
