If you don't periodically log into an email address you only use for bitcointalk a hacker might use it to hack your account here.
To solve the problem change the email address in your profile to one that can't exist because it has an invalid domain name. I just changed mine to
[email protected]. Bitcointalk accepted it as a valid email, but the domain
.exist is invalid, so a hacker can't use it.
Stake a bitcoin address you control
here before changing to an invalid email address.

https://www.onmsft.com/news/your-outlookcom-email-account-name-will-be-recycled-if-inactive-360-daysAccording to a new report by PCWorld, Microsoft is recycling Outlook.com email account names if they are left inactive after a certain period of time. Microsoft has made no mention that this recycling of account names would occur, but the company’s Services Agreement does state that you are required to log into your account “periodically.”
“The Microsoft branded services require that you sign in to your Microsoft account periodically, at a minimum of every 270 days" ... Microsoft’s Services Agreement states.
When an account becomes inactive, Microsoft will queue that account for deletion. Once that happens and after a total of 360 days, Microsoft will allow that email account name to be available to the public again.
Yahoo faced criticism over this unused email recycling issue in the past, which sparked an outrage over privacy and security concerns over identity theft
