SharePoint Online External Sharing: blacklisting overrules whitelisting

Via the configuration capabilities of Office 365 SharePoint Online External Sharing, the SharePoint administrator has full control to both allow and disallow specific organizations by domain. Be aware that the 'disallow' configuration has higher prevalence then the 'allow': if you run into a situation that you cannot invite a guest account of whitelisted domain, then check your blacklisting (on tenant plus site collection level) whether the organization domain is also listed there.
Result: blacklisting overrules the whitelisting allowance
