The only way for someone to see these emails is if they somehow manage to gain entrance through hotmail itself (steal user passwords) or find out your password to log-in (guess). Very unlikely will someone hack into the hotmail host. More likely they guess your password. That is why you keep your password different from all other passwords, and difficult to guess. the passwords '1234'
, and '1111'
are all very easy to guess and shouldn't be used. A good one would have a capital letter, and number, and another character, such as ! or ~, as well as other letters. Some people make it really complicated such that the hotmail password doesn't form any real words. Long ones are good too. These can be difficult to remember. '!gggetjhh#2w85#20)' would be insanely hard for a hacker to guess (not suggesting you use any I post on the internet, however).
Once you delete an email, it goes to your deleted section and stays. You can still read it, as well as anyone with your password to your account (potential hackers). If you delete it also from the deleted section, no one can ever see it or find it: it is as if it never existed.
Notice that I have 19 deleted items that are still available, that need to be further deleted from this folder:
