Even if you are a regular Hotmail user, your Hotmail account might go missing for some reasons. Outlook.com is a modern cloud email service from Microsoft. If your existing @hotmail.com, @live.com or @msn.com email account is missing, then the best thing to do is make sure you enter the right password. You can get a new account if you want.
Just remember, the problem of your Hotmail account missing may be because there was no single activity from your Hotmail account from past 360 days. Hotmail will automatically delete or your account will automatically expire after 360 days without any activity. If you do not use your Windows Live ID for a year (365 days), it can be permanently deleted. So, make sure you use your Live ID from any service you want Mail, Skype, Sky Drive and others. Otherwise, some other person can get your username. That means, your Live username will be available for new registration.
In order to avoid your Hotmail account from missing or being expired, you have to log in to your Hotmail account in every 8 months. And even if you are a frequent user and then your Hotmail account is missing, then probably, it has been hacked or someone has changed your password. Reset your password if that’s the case. Make your password filled with special characters and numbers so that it will be more secure.
And if you do not want to take risk and you are willing to spend some money, then you can use paid version your Hotmail account. Paid Windows live account will remain active for the whole subscription period. You will not have to face the problem of expiration or missing account even if you don’t access your account for over a year. Prevention is better than cure. So, you better install updated antivirus to get rid of Hotmail virus from spam emails.
