Hi, there are a lot of reasons that email fails. There’s a current issue with non-SSL domains and Outlook.com for instance: https://buddypress.org/support/topic/buddypress-emails-not-going-out/

If you’re not receiving any emails from your WordPress site, start by testing your site setup with this plugin: https://wordpress.org/plugins/check-email/

In any case, we’ll need more detail, like what the user’s email address domain is, to help you troubleshoot.
