Hi Tina,
If your organization has a Microsoft certifications benefits, you just need to link/associate your organization email address to your certification profile to claim the discount.
If you don’t have a certification profile yet, you may follow the steps below:
1. Go to microsoft.com/learning
2. Click “Go to Certification Dashboard” (make sure that there is no account signed in)
3. Sign in using your Microsoft account/Personal Email and password.
4. On your dashboard, click “Edit your certification profile”
5. Enter your information (Note: Make sure to enter all information with red asterisk * sign)
6. Click “Save” (this will generate the MCID) then click on “Continue”.
Furthermore, If you’re still unable to claim the discount, please try the troubleshooting steps below:
Make sure you have the latest browser (Edge/Chrome/IE or Mozilla Firefox)
Try using your browser in InPrivate/Incognito
Clear browser cache and cookies

Sign back in to your Microsoft Certification profile and try to update/schedule your exam.
