My email address is (somebody) @webtv.net.
Since webtv ceased operations decades ago it is kinda amusing when I am notified that webtv is having technical issues.
So I AI'd it.
If you had a WebTV email account, it's important to note that the service officially ceased operations on September 30, 2013. This shutdown included the discontinuation of all associated services, including email access. Therefore, you will not be able to receive emails at a WebTV address anymore.
However, prior to the shutdown, Microsoft allowed users to migrate their data and accounts to their Outlook service. If you had followed this process and migrated your WebTV email to Outlook.com, you would still have access to your emails through that platform.
To check if your WebTV email has been migrated or to recover it, you can visit Outlook.com and use the "Can't access your account?" link for assistance.
If you did not migrate your account before the shutdown, unfortunately, your WebTV email is no longer accessible.
