I have opened a Premier support ticket with Microsoft and it is true, that this is not working anymore. 

Waiting on the escalation team.

    AlexandrosAP Did you ever find a resolution to this? I am encountering the same behavior (modifying ExceptIfRecipientDomainIs via PowerShell does nothing and the existing domains in Purview are listed in AdvancedRule) and was wondering if you found a solution.

      This need to use Advanced rule,.And ExceptIfRecipientDomainIs does not work .Need use like this,

      "Operator": "Not",
              "SubConditions": [
                {
                  "Operator": "Or",
                  "SubConditions": [
                    {
                      "ConditionName": "RecipientDomainIs",
                      "Value": [
                        "condoso.com"
                      ]

       

      Recommend use Not RecipientDomainIs
