no probably not. i suggest that if this is a shared computer you create your own account on the computer with a password. you can do this by going to control panel user accounts. make a new account for yourself password protect it make sure it is an administrator account. remove your email account from your email client on the old account and create it again on the new account. you can use the export function to move your existing emails and contacts to a temporary file and then use the import function to move them to the new account.
I dont believe you can retrieve emails that have been deleted from the deleted account. This will keep anybody else from having access to your email in the future. you might also want to change the password on the email account. you have to do this through your isp.
