Hi luis,
Thank you for contacting the Microsoft community.
Your dedication for the Microsoft Credentials is Genuinely appreciated as I understand that you encountered an issue when trying to schedule your AZ-104 for renewal to earn your AZ-305 Certificate. Allow me to provide the best options to proceed.
For us to verify your profile and provide the best option to proceed, kindly share the requested information through the private message that I initiated.
Furthermore, since you are trying to renew your expired AZ-104 Microsoft credential by scheduling the same exam. This occurs because the Online registration system still recognizes your initial exam. The solution to this issue is by calling Pearson VUE directly to schedule your exam offline. We also advise not to mention the specific error you received, as this could prompt the testing center to direct you back to us. Our engineering team is aware of this issue and is actively working to have this resolved.
Moreover, if you are an ESI learner or you want to use a company discount which is a part of the Enterprise Skill Initiative program, the best option to proceed is to reach out to the ESI support team on their ESI support Contact page as they are the ones with the specialties to deal with issues faced by ESI learners.
