Outlook Express error message when sending/receiving

Receiving the following error message for one user in an office of 20 w/same email settings:
Your server has unexpectedly terminated the connection. Possible causes for this include server problems, network problems, or a long period of inactivity. Account mail.msy.bellsouth.net Protocol Pop 3, Server Response '+OK 19371 octets. Port 110. Secure (SSL) No. Error. Number 0X800CCC0F

i've disabled norton internet security, added msimn.exe to the allowed apps, rechecked the settings to everyone else.  I've attempted checking and unchecking Server requires secure password authentication and  my server requires authentication w/the correct credentials but this user is still receiving this error message.  When the send/receive beings the message of downloading 1 of 84 beings but stops w/the error message.  i setup the email account on another PC and all the emails came in.

the only thing i have not yet done is to reinstall Outlook Express, but wanted to know whether I was missing something before I attempted.  thanks.

Hi mdmcq5,

Reset the account. Copy the account info. Delete it. Re-create it.

There may be an a corrupted or unually large file in the first message.  Try to see and remove the stuck message here:

I've reset, deleted and recreated the account on the PC.  There do not appear to be any corrupt files and the emails DO download when the settings are put on an entirely different PC.  That was leading me to believe either her Outlook Express needs to be reinstalled or there was something i was missing on the Symantec Internet Security, even though I disabled it.

Do you have virus check on the account. Disable that and see if the emails will download.  Check if popup blocker, spyware scanner, or ad blocker are interfering with the download. Disable one at a time.

If no joy, reinstall Outlook Express. That is easy to do.

I've disabled everything, and am figuring reinstall is the last resort...unless something else comes to your mind??

what's the easiest way to reinstall OE w/out lossing the users inbox emails?

With Outlook Express, you usually do not lose data when you re-install.  But it is safest to backup the data first.  Find the file where the *.dbx data are and copy it.

I assume you have Windows XP.
