sbs2008 pop3 email problem

I have a SBS2008 server downloading pop3 email to individual users, the  event log for 1 of the users keeps saying:

"Because of transient or unknown failures, one or more messages (76) could not be delivered to 'fredsmith@domain.com' on the SMTP server 'localhost'. The messages will be left on the POP3 server. If these failures continue to occur, you can either connect to the POP3 account and retrieve or delete the messages manually, or resolve the problem causing the errors. For more information, see the log file at "C:\Program Files\Windows Small Business Server\Logs\pop3connector\pop3service.log".

1. I have logged on to webmail and deleted all the email in the account.
2. I have deleted the webmail account and re-instated it.
3. I have setup Outlook on my personal computer to connect to the pop3 email account    with (delete mail on server ticked) and nothing comes down!

Yet the Exchange server event log keeps saying there is 76 emails !!
Please kindly help
Thanks
Sam

Manually remove the pop3 connector:

Log on as an administrator to the server that is running Windows SBS 2011 Standard.

type cmd

Navigate to %programfiles%\Windows Small Business Server\Data.

Type del pop3records.dat, and then press ENTER.


If the file does not exist, the Command Prompt window returns a message that says, “Could not find <filename>.” Continue with the next step.

Type net stop pop3connector, and then press ENTER.

Type sc delete pop3connector, and then press ENTER.

Change directory to %programfiles%\Windows Small Business Server\Bin.
Type pop3connector –install, and then press ENTER.


Add the accounts back in and test.

ok what you have said doesn't stack up.

SBS is only reporting what the POP server is telling it.

Stop/start the pop3 service on SBS if as you have said there is no mail in the pop3 box then you wont have a problem.

I restarted the pop3 service - still had the problem
I rebooted the SBS2008 server - still had the problem

Now here is a really strange problem:
I put in the incorrect password to the pop3 account that was causing the problem
expecting the error message to be replaced with an incorrect credentials messages, but I got two error messages the same 76 messages error above and a bad credentials message.

So the problem is in the exchange server somewhere!
