In Outlook 2003, I can't send or receive emails. I keep getting error message 0x8004210b - re operation timed out waiting for a response from the recieving (POP) server. I have contacted my ISP who has checked out my email settings (which by the way work on my laptop). The ISP technician suggested I reinstall MS Outlook which I have done. Microsoft suggests that I might have a clash with my email anti-virus program (which is Trend Micro P-Cillin Internet security 2007). Outlook runs and opens, the calendar updates but the emails just stopped sending and receiving at the end of April. In desperation I set up an account in Outlook Express with the same settings and it worked. I am connected to the internet via an adsl router modem. There are two other computers on the router all receiving and sending emails. I still think its a block somewhere from P-Cillin but can't prove it. My subscription is ending in the next few weeks for P-Cillin internet security so I thought I might not renew and take it off the computer. But remembering the problem I had with removing Nortons on another computer last year I also would like advice before I try to remove P-Cillin Internet Security. Any suggestions to get the emails going again would be welcome or help in removal of P-Cillin.
