Arindam_ThokderI found the issue that is causing the Microsoft DMARC reports to fail RFC compliance about 1% of the time (https://www.uriports.com/blog/dmarc-reports-ietf-rfc-compliance/). Sometimes the reports have empty elements for domain and selector DKIM auth results.

 

 

RFC7489:

 

   <xs:complexType name="DKIMAuthResultType">
     <xs:all>
       <!-- The "d=" parameter in the signature. -->
       <xs:element name="domain" type="xs:string"
                   minOccurs="1"/>
       <!-- The "s=" parameter in the signature. -->
       <xs:element name="selector" type="xs:string"
                   minOccurs="0"/>
       <!-- The DKIM verification result. -->
       <xs:element name="result" type="DKIMResultType"
                   minOccurs="1"/>
       <!-- Any extra information (e.g., from
            Authentication-Results). -->
       <xs:element name="human_result" type="xs:string"
                   minOccurs="0"/>
     </xs:all>
   </xs:complexType>
