Hi Peter,

You probably have multiple Exchange on-premises forests? if yes, get the GUID value from on-premises Get-OrganizationConfig or cloud's Get-OnPremisesOrganization and use it for the Get-IntraOrganizationConfiguration -OrganizationGuid <GUID> command, see cmdlet documentation here: Get-IntraOrganizationConfiguration (ExchangePowerShell) | Microsoft Docs
