My Microsoft certification exam voucher shows “Already used” even i didnt.

Submit a Microsoft Credentials Support request to have the voucher’s redemption record checked; a public Q&A thread cannot access or verify voucher usage.

Submit the voucher investigation

1. Open Credentials support and select online support request. ^1^
2. In the request form, select:
   • Product family: Learning
   • Product or Service: Microsoft Credentials
   • Category: The closest available voucher, discount, or exam-registration category
   • Type of Support: Professional No Charge
   • Preferred contact method: Email
3. Include:
   • Your Microsoft Learn username.
   • Exam name and code.
   • Voucher code—enter it only in the private support request, not this public forum.
   • Date the manager approved or assigned it.
   • Date and approximate time the Already used error appeared.
   • Screenshot of the approval/assignment and screenshot of the error.
   • Microsoft account used to reach Pearson VUE, plus any existing appointment/order details.
   • A direct request to confirm when and against which certification profile or appointment the voucher was redeemed, and to correct an erroneous assignment or redemption.
4. Submit the case and retain its case number. Credentials Support is provided by email, even if another contact option is selected.

Microsoft directs other certification issues to Credentials Support, while appointment or scheduling issues are handled by the exam delivery provider. ^1^ Similar cases where an unused voucher displayed Already used are also routed to the certification support team rather than resolved in Microsoft Q&A. ^2^

If the problem is with the Partner Center assignment

If Credentials Support finds no redemption but the manager’s Partner Center record shows the voucher assigned to the wrong user or code, the authorized user who made or manages the assignment should open a Partner Center support request:

1. Sign in to Partner Center with the organization’s work account.
2. Select the AI assistant icon in the upper-right, describe the voucher-assignment issue, and select Contact Support.
3. If AI assistant is unavailable, select Help (?) → Contact Support.
4. Choose the relevant workspace and problem type, select Review solutions, then Create support request.
5. Attach the approval and assignment evidence and include the Credentials Support case number. ^3^

Do not post the full voucher code, account email, order number, or other personal information in this public thread.
