POP3 connector not working on SBS 2008

I'm having problems setting up the POp3 connector in SBS 2008 Standard x64.

On Friday I had 5 out of 8 mailboxes receiving mail - I think the missing 3 were wrong passwords/usernames.

I've corrected these today, but now no emails are being pulled through. I've scheduled this to collect every 5 minutes and when I do a Retrieve Now it takes about 5 minutes before saying it finished with errors.

I've normally set up SBS 2003 servers using POP3 with a Global Mailbox and never had any problems. With this one I have connected the mailboxes individually.

The emails are lurking on the ISP's mail server and I can't understand why they are not being pulled down as the usernames/passwords to authenticate them are now correct.

Thanks in advance for any ideas.

Try increasing the schedule to 15 minutes as a test. If there is a large e-mail it may be timing out before complete. SBS 2003 had a 15 minute minimum for this reason.

Are there any related errors in the event logs?

Good point, this servers Internet connection is the slowest I've come across in a long time - 512k max because of their location. Obviously won't affect 99% of emails but any really large attachements will be a problem.
I've set to 20 minutes to test.

Do you have the option of receiving e-mail via SMTP directly rather than using the POP connector? Though the POP connector can be used indefinitely it is really intended as a temporary solution wile migrating from POP to SMTP.

I've given it 45 minutes now, 20 minutes for the next download and 20 minutes to download and it's still not budging the emails on the ISP's server. Not a huge amount and, having checked, none with big attachments.
I have tried stopping and restarting pop3 service and nothing obvious in event viewer.

Hi,

Do you have verbose enabled? If yes what are the results?

Also can you try adding recipient policy as mentioned in

With so few mailboxes I would prefer to get the POP3 connector working first, then when I have everything working I will make the changes to allow SMTP.

Understandable.

Have a look at the log located:
C:\Program files\Windows Small Business Server\Logs\pop3connector.log

Thanks Yogs - I get an error in each POP3 account in the log file. This is one mailbox:

is not mail.btconnect.com the SMTP server? Don't you want pop3.btconnect.com  ?

Commented:
Yes, absolutely. Guess I've got too many connections where both are mail.xxxx.com.
Many thanks
