Hotmail account – lost all emails, folders and contacts

I have had my Hotmail account for 11 years but have not used it as frequently recently due to Hotmail being banned where I work. I logged into my account yesterday and found that all of my emails, folders and contacts had been deleted. I understand from the Terms that this has probably occurred due to me not accessing my account for 270 days. I did not realise that there was this condition or that it had been that long since I last logged in. Is it possible for my emails, folders and contacts to be restored ? I would really appreciate it, I feel quite upset that I have lost all of my historical emails. I have used my Hotmail account all over the world. I will ensure in the future to log into my account more frequently, now that I know that this can happen. Please help.
