I've been testing SP3 for Exchange 2007 in SBS 2008 in my test environment. After a couple of days, the POP3 connector wasn't retrieving the mail and was giving errors (see below). It asks to verify the account settings (verified), and to check the internet connection is working properly (yes). So if I restart the server, it comes back fine - then a couple of days later the same thing occurs all by iteself.
The error is:
[t 0] 11/10/10, 19:18:16: EVENT: An error occurred while accessing the mailbox for user [my email address] on the POP3 server [my mail server]. The error code was 0x800ccc0d. Verify that the server and account settings are correct, and that the internet connection is functioning properly.
A few different google searches have turned up nothing except "check your internet connection" (it's working fine). Obviously, restarting the server every time this occurs is not feasible.
Has anyone else seen this problem before, or have any ideas how to fix it?
Can you still telnet to your pop3 server?
telnet <pop3.mailservr> 110
