I have Office 365 on my work private computer and also on my work public computer.  My work public computer (at the front desk and used by my employees) has access to Skydrive through Word and Excel and I don't know how to stop it.  I do NOT have Skydrive installed on my work public computer.  But since Word and Excel is on my same Office 365 account, it is sharing the Skydrive files.  How do I make it not have access to my Skydrive files?
