help with blocked account?

Hi my problem is a few weeks ago a friend asked for my help unlocking her email account, it had blocked because her old email address that she used as a security measure had been deactivated due to it being a works email address and she no longer works for them.. so we sent a message to Microsoft to get the account unlocked and to explain the situation but in order for them to reply they needed an email address so I used mine. My problem now is I have been sent a link stating that her account can now be reactivated but as part of this process her old security info will be deleted and your contact email will be (mine) instead.... does this mean when my friend reactivates her account she can get into my email account ... if not could this affect my email account  ... Please help.  Thank you.
