C.B. - 2012 is better, glad to hear you updated.
yeah I think there's a disconnect (could be me too though) I've been around eMail forever, but only recently started using WLM.
Rules are global, they get applied to every "account" - they aren't really attached to one account.
Email Rules Tab: Create a new rule for your POP email account(s)
it's (plural) - the conditions and actions defined in the rule determine when and what gets done
So, the example I previously provided should do the trick for you. Minor rules tweaking might be required based on your requirements - you might for example choose to download the msgs and move them to a special folder instead of not downloading them or you might decide to just delete them - there are many options.
The account selection is in the conditions of the rule - mark that condition (from a specified account) and a dialog box should appear with a drop down box where you can select the account for the condition test.
There is one error in my previous example - if you select "Do not download from server" you cannot select "Stop processing more rules" - by not downloading, you essentially stop processing more rules.
Accounts are "linked" to eMail servers. It is wrong to think all eMail goes through MS servers. Take a look at the properties for each of your accounts and you'll see provider specific servers for POP and SMTP for each account.
Oh, make sure you reset sbcglobal.net to be your default. Here's the rule I built
Let me know how you make out or if you just decide to eliminate outlook.com
