I am new to windows live mail and when I try to check the status of downloaded messages on windows live, another window pops up, perhaps that's status window. On the bottom right corner of this window is an image like that of a pin, which tilts when clicked.

What exactly is this pin and what's the purpose of same?

 

When I open Outlook I have to hit send/Receive and then hit send/receive again to start downloading new messages. That's the way I want it.  But now, as I'm reading the downloaded messages and dealing with them, new messages keep coming in and I lose track of what I looked and what's new and coming in automatically. I'd like to have outlook download new messages ONLY when I tell it to and not just constantly when Outlook is open. Anyway to do that?  Outlook 2010 running on Win 8 Pro.

Thanks,

Steve
