[Cube] Email downloading with Entourage

[Helen Lowe]

Hotmail/Entourage problem

I have recently installed Office 2004. I have a problem with Entourage 
downloading from Hotmail.

A downloading session just seems to fall over at a particular occurrence:
Downloading an email from a messaging group that I authored myself and sent 
to the group (eg this one).

I get the message: An unknown error (-50) occurred. Could not retrieve mail.

Any ideas for a fix?
Much thanks for your thoughts...
