1 of 2 email accts not pushing to phone

I have two emails set on my 8830, a primary (A) in which I get all my work emails, and a secondary (B) for personal. This weekend, (A) email quit pushing to my phone. The emails are on the server and on my outlook, but not in my (A) inbox. I have resent the service books twice and DO get those messages in the (A) inbox and I can send emails from there also but cannot receive test emails. I spent a while with verizon tech support but could not remedy the situation. (B) is working perfectly. Any recommendations?
