Outlook Express Identity Problem with Email recovery

I am running Outlook Express on an XP machine. We have several identities.
One identity is suddenly having trouble. We have deleted and reloaded the
identity. The ISP has helped to make sure all is good on their end and mail
can be recovered on their Web Mail site. When opening this one identity we
receive two errors ending with 0F and 92. The software is definitely finding
the server and seeing the number of emails that it needs to load but the
connection terminates and the errors are announced rather than loading the
mail. The other identities are fine. Any ideas?
