could problem version of api? there problem nvp request?

i ran same problem , contacted paypal technical support , solution error 580023 normal behavior when name fails match email of paypal account. confusing because there nothing wrong @ request, contrary response message implies. example, if having same issue need change john doe first name , last name of user associated paypal email trying match against.

transcript convo paypal mts:

"the error receiving expected. in order response of verified or unverified, name provide must match email address provide."
