How do I recover my deleted hotmail account on my iPad

Deleting an email account from your iPad will delete all associated mail messages. Assuming that your MS Hotmail account was using IMAP, all your email will reside on the mail server. Simply re-adding the mail account to your iPad will restore all mail to your iPad.
