Analysis:

A

Please provide the output for nslookup for lyncdiscover and for the below PS commands:

Import-Module SkypeOnlineConnector

$userCredential = Get-Credential

$cssession = New-CsOnlineSession –Credential $cred –OverrideAdminDomain "ssas.org"

Import-PSSession -Session $cssession

The workaround for this issue is to use the global admin account on .onmicrosoft.com domain instead of ssas.org.
