its more then likely to improve security.
Personally I am transitioning to gmail as you will never have issues.
We have had problems over the years with yahoo/rogers email address,login,password prompts.etc within outlook.
Try and transition to gma...
yahoo.com....wrong password.....rogersmembercenter.com... wrong password.
Forgot password option useless as it gives popup window asking secret questions..I NEVER MADE secret questions ever PERIOD.
I called rogers on phone and they have no idea ...
