Recently upgraded from Office 2000 to Office 2010. My Outlook program no longer receives mail. Outbound mail work find but when system tries to download new mails, it displays status as if individual mails are coming across and errors out on the last mail on the status bar. Get a send/receive error and no mail becomes visible in my inbox. Ports are set at Incoming 110 and SMTP is at 25. Error display it "Task 'e-mail address' - Receiving reported error (0x80040154) :'Unknown Error 0x80040154'. Any ideas?
