All emails going to 2 different email accts.

My #1 email acct is a POP acct with my internet server.

M #2 acct is my windows live acct.

I actually set up my windows live.com first for my Microsoft Account, then added my POP acct. I prefer using the POP acct.

I've always gotten very little mail on my #2 acct, usually just from people or addresses I communicate with only on that acct.

Suddenly last week, I started receiving all my emails on both accts.  I've checked my servers on the POP acct, changed the default acct from POP acct to the Windows Live acct.  Copied or exported as many emails as I wanted to keep and deleted all the rest. Even tried reinstalling the WL acct.

My server Tech Service had me change some settings, etc, but nothing changed and he said he couldn't help me with Live.com and to contact Microsoft.

So, can anyone explain why I'm having this problem and what I can do to correct it?

Will appreciate any / all advice
