I cannot assist with account recovery or voucher status inquiries directly. If you are encountering a message stating that the user does not exist, it may indicate that your account was deleted or that there is an issue with your profile. I recommend reaching out to Microsoft support or the specific community support for the Fabric Community to resolve this issue. They will be able to confirm the status of your DP-600 exam voucher and assist with restoring your profile if necessary.
