I have been an Outlook user (accessing POP servers) for over a decade.
My system has been stable and unchanged for several years (read: no new software), with the exception noted below (reloading Outlook).
My Outlook 2002 client has suddenly stopped sending messages to selected email addresses (not all addresses). These messages simply sit in my Outlook Outbox, regardless of multiple attempts to send them. The “blocked” messages seem to be the addresses of frequent email correspondants. While these messages remain unsent in my outbox, other messages will be promptly dispatched to other addresses. And occaisionally I can get a message through to a “usually blocked” address.
My Outlook client is configured to access a single POP server account for send/receive messaging.
I have tried using the “repair” routines on the MS OFFICE original OEM disks. I have also reloaded Outlook from the original OEM disks. No impact from either strategy.
Any ideas out there?
