Oh yeah Outlook.
I'm using 2010
This issue is recurring, and affects predominantly, but not solely, MS Outlook users. Also seen reports from Thunderbird users. It is extremely intermittent for most people, and most clients. I occasionally see PW errors in my Mercury/32 (a comprehensive mail server application) logs. But Mercury is set to poll POP3 servers periodically, and just fails the one connection attempt, then polls the server again on the next polling cycle. I've never seen the errors on successive polling cycles. Usually just one error every couple of days on one single poll, of several throughout the day.
I've given up trying to offer help because I can't see that anybody has found a fix. It is just something flaky with the servers, and my method of access is actually masking the errors.
