I previously used Windows Live Mail on another laptop, and it worked fine.  I had it set up so that it only checked mail when I clicked on "Send/Receive".  As a result, it never checked mail upon startup, only when I clicked the "Send/Receive" button. 

Now, I've changed to a different laptop.  I set up Windows Live Mail the same way.  I UNchecked "send and receive messages at startup" and I also unchecked "check for new messages every xx minutes."  While it does not check for messages once the program is running unless I click on "Send/Receive," it DOES check for new messages at startup.

I do not want it to check for new messages at startup.  I did not do that on my last computer but it does on this one, despite my unchecking the appropriate items.  I am using the same operating system on both computers (Windows 10).  Why is this happening?

I use a variety of IMAP and POP3 accounts and all behaved normally on the previous computer (none checked mail at startup) but they are not behaving this time.

What more could be at play here?  I don't want to uncheck "include this account when sending/receiving", as I do want it to do that when I click on the send/receive button.  Just not when the program starts.
