<P>My Distributing POP3 Client has been set to download mail for three accounts on my ISP's server.  Two are working correctly, but one results in the message "File creation error. - Network Error; delivering anyway." when polling takes place.  There is mail for that account, but it is being left on my ISP's server.</P> <P> Any ideas what may be causing this and what the solution might be?</P> <P>Prior to this, all accounts have functioned correctly for many months.</P> <P> Thank you</P> <P>GordonM</P> <P> <U><STRONG>Further Comment</STRONG></U></P> <P>Further to the above, I have now set up a normal POP3 account on Outlook Express for the problem account.  This manages to pull down all of the mail except, possibly, one message.  I receive an error message, saying:</P> <P> <FONT face="Times New Roman" size=3>Message number 1 could not be retrieved. Account: 'pop.broadband.rogers.com', Server: 'pop.broadband.rogers.com', Protocol: POP3, Server Response: '-ERR problem retrieving message.', Port: 110, Secure(SSL): No, Server Error: 0x800CCC90, Error Number: 0x800420CD</FONT></P> <P>Maybe one of the messages on the server has been corrupted.</P> <P><STRONG><U>Problem Solved</U></STRONG></P> <P>It seems that there was a problem with one message on the server.  I downloaded all of the messages for the problem account, without leaving messages on the server.  I then received the error message noted above.  I then went into the account using my ISP's webmail app and one message was left behind.  I delted this.  I then sent a test message to the account and Mercury was able to download it.  I have no idea what was wrong with the message that I had to delete, as I had no means of analyzing it through webmail.</P> <P mce_keep="true"> </P>
