Sending, receiving, and organizing email in Outlook.com
Hi!
Either something is blocking Discord emails in your email, or they aren't being sent at all.
Are you sending the password reset email through the Discord Website, Discord Desktop, or Discord Mobile? Try sending the email using all three methods.
Also check your spam folder.
Also try accessing your email in another Outlook account, such as the app, and see if the problem persists.
