Hi Dhaval,
Thank you for contacting the Microsoft Community.
I understand how important it is to redeem your event-attendee certification discount, and I want to ensure it's applied accurately and without delay. I’m taking the necessary steps to get this addressed promptly so you can make full use of the opportunity you've earned.
One way to apply the discount tied to a different email address is by linking that account to your Microsoft Learn profile. You can refer to the guidance in this article: Manage your Microsoft Learn profile settings | Microsoft Learn for step-by-step instructions on how to add another account to your profile.
Please note that you can link up to five work or school accounts and one personal account to your Microsoft Learn profile, giving you flexibility in how you sign in and apply offers.
If both of your email addresses are personal accounts, and neither has an existing certificate associated with it, we recommend using the email address originally used to receive the offer—as that’s the one best aligned with the discount eligibility.
For additional guidance on scheduling exams and applying discounts, you may also refer to the Vouchers and redeeming discounts | Microsoft Learn page.
If you need any further assistance or clarification, please don’t hesitate to reach out. Additionally, feel free to share any specific details related to your concern—such as the event you attended—so we can explore all available options to support you effectively.
I look forward to your response. Please note that if no response is received after two business days, the case will be closed and locked. After the case is locked, we will no longer be able to respond. Thank you.
Best regards,
