POP mail download not working in Outlook 2010

POP mail download not working in Outlook 2010

I have a problem using POP3 in Outlook 2010. I tested IMAP and that seems to work, but I prefer POP as I use only one PC and want to keep all mail locally. I checked all settings many times, but I see no wrong settings. The account check of Outlook is positive. Access to the POP server is OK and sending to the SMTP is OK.
But when I try to download the messages only a few message arrive as flat ascii without header. Most of the messages are not downloaded at all. After some time I get the error message:

Taak han@katteman.nl - Ontvangen... rapporteert fout (0x80042112): De volgende e-mailberichten op de mailserver kunnen niet worden opgehaald. Neem contact op met uw internetprovider of e-mailbeheerder als u deze foutmelding blijft ontvangen.
7764940000000009085
7764940000000009153
7764940000000009175
...

So error (0x80042112) and messages not retrieved.

I tried several other email clients.
1. EssentialPIM works well with POP3
2. eM Client does not work at all.
3. Windows live mail does not work with POP3
4. POP Peeper has no problems with POP3

I have no idea what to do next.

With kind regards,
