how can I resend a confirmation about certification completion

Use the Microsoft Credentials Support channels to have the confirmation resent or reissued.

For Azure training and certification-related confirmations (such as virtual training days, exam results, or certificates):

1. If the issue is about a virtual training day registration or confirmation email that was not received or needs to be resent, contact Microsoft Credentials Support using the official support entry point:
   • Go to the Credentials Support portal described in the context (for example, the help entry at https://learn.microsoft.com/.../credentials/support/help).
   • Sign in with the same account used for the training/registration.
   • Open a support request describing that the confirmation email needs to be resent.
2. If the issue is about a certification exam completion confirmation or certificate (for example, AZ-900, MS-900):
   • First, sign in to Microsoft Learn and check the Profile → Credentials → Certifications section to confirm the certification is listed.
   • If the certificate or badge is missing or cannot be downloaded, open a ticket with Microsoft Credentials Support:
     • Use the https://aka.ms/credentialssupport entry point referenced in the context.
     • Sign in with the same account used for the exam.
     • Complete and submit the support form, specifying that a certification completion confirmation/certificate needs to be resent.
3. For issues where Pearson VUE confirms the exam was delivered successfully but the certificate or confirmation is not visible, Microsoft Q&A moderators explicitly direct users to Certification Support at https://aka.ms/CertificationSupport or the Credentials Support portal to have certificates and confirmations reissued.
4. For course completion on Microsoft Learn (self-paced modules/learning paths), note that there is no formal certificate for course completion; only badges and trophies are provided. In that case, a “confirmation” is typically shown as achievements in the Learn profile rather than a resendable email.

In all these cases, resending or reissuing confirmations is handled by the Microsoft Credentials Support team via the official support portals, not directly by users.
