When Norton uninstalls, it leaves your machine littered with parts of itself that can affect many things, most particularly Outlook. \\Steve// From: Clayton Doige [mailto:[EMAIL PROTECTED] Sent: Thursday, July 03, 2008 8:52 AM To: MS-Exchange Admin Issues Subject: OT Outlook POP Error 0X8004210A All, sorry for the OT, I have a groups of four people who's pop email all stopped working about a week ago. When they send/receive the error in the subject comes up. Google reveals that this is due to Norton/McAffee blocking Outlook. In this case Norton is not installed, they are using AVG. I have had one of them turn off Windows Firewall and stop the AVG services and they still get the error. From a command window they can telnet to the mail server on port 110 and login, list, retrieve etc. If I had hair I would be pulling it out, and was wondering if anyone has any experience of this and can give me a few pointers.
