I can verify that the email address in question is perfectly valid. I cant tell the actual cause of the error. Thank you for helping me out here.

I think it's complaining because XML (and therefore SOAP) is case sensitive. "emailaddress" should be "EmailAddress". Your emailaddress key just happens to be first so it's throwing the error there. Here is the full example:

    <CreateRequest xmlns="http://exacttarget.com/wsdl/partnerAPI">
        <Objects xsi:type="Subscriber">
            <ObjectID xsi:nil="true">
            </ObjectID>
            <EmailAddress>[email protected]</EmailAddress>
            <Lists>
                <ID>123</ID>
                <ObjectID xsi:nil="true">
                </ObjectID>
            </Lists>
            <Attributes>
                <Name>First Name</Name>
                <Value>Lee</Value>
            </Attributes>
            <Attributes>
                <Name>Last Name</Name>
                <Value>Cruz</Value>
            </Attributes>
            <Attributes>
                <Name>Company</Name>
                <Value>Northern Trail Outfitters</Value>
            </Attributes>
        </Objects>
    </CreateRequest>
