Outlook Express problems..at work I had a new email account created for me i'd been using a former employees?

I can receive some emails from certain contacts but not from others. I also tried sending an email from my yahoo account to my account on outlook %26amp; it would not go through. I had no problems with the other address i was using..think it may be related to changing the email address? Any help??Thanks

Make sure your spam filter isn't blocking emails. Ask your IT staff at work if they are using a spam filtering service like MXLOGIC. That service may have identified sources (your contacts) as being a spammer.
