I sent my brother a link to one picture on my Skydrive. He phoned to say thank you and said it was great how on his ipad (not on his iphone or laptop) he had access to all of the pictures within the folder. On further investigation (I went to his house to investigate this) it turns out that my link to one picture actually has given him access to not only my entire Skydrive content but my Inbox, my Contacts and that infact the page he viewed the picture in was an entire outlook account of mine! It isn't happening on his iphone or laptop only on his ipad.

Needless to say I deleted permissions  (made no difference) and then deleted the actual email. I cannot express how alarmed I am at this. I now expect any sharing to result (on an ipad) in complete access to my account.

Please tell me what's going on!
