I made a hotmail account a very long time ago and this was my main email, I used it for everything. However about a year ago, I tried to log in and found out that someone had tried to access my account (I think this is doubtful however, I think it was me getting my password wrong or something) anyway, I have tried numerous times to fill out the account recovery form and (bearing in mind this account was created like 5-6 years ago) I've forgotten most of my account information, such as previously sent emails, subject, etc. and I keep getting the 'there wasn't sufficient information for us to validate your account ownership' email reply. I've got by for a while now, transferring my mains emailing needs to a newer account, however I haven't been able to change my xbox live account email address and now it's kind of playing up. Is there anything I can do, even though I've forgotten too much of my info, to get my accounts back? 

Thanks for reading if you do
