Windows live Mail calendar setting

I want to know how to make a setting change to Windows Live Mail without the risk of losing this e-mail service.  The setting involves Calendar Service which I do not use, however the current setting affects the receiving of messages.  I get 2 drop boxes and an error message every time that I logon  to view messages.  An error occurs when attempting to connect  to Windows Live calendar Service.  Windows 7 is the operating system on this computer.
The question is, how can I make calendar Service setting changes to Windows Live Mail?

Hello Vern,

I would recommend you to contact Microsoft support to get this clarified.
Thank you.
