My boss is using Microsoft Outlook SP2 for his emails (XP Pro) - he knows of 3 specific email addresses who are not receiving his emails. No bouncing, no errors. When I remove his email accounts (he has 2) and add them back in - exactly how they were profiled before - he can send for a short period of time and those 3 accounts will get his emails!? He does not install programs or do anything different that stops the emails from going out. He only has one anti-virus program running (Symantec). Every time I send these same 3 email addresses a test message - they receive it. My boss and I are using the same mail server as well. When I do go to his webmail and send they receive all of his test emails. Any suggestions?
