How do you update http mail store in Outlook 2003

[amos]

I recently updated from Office professional 2003 to 2007 but as 2007 cannot
be read by earlier versions downgraded back to 2003. I have now lost my
Hotmail connection in Outlook with the message 'http mail store could not be
properly updated'. Can this be rectified and if so How ? Any help gratefully
received.

Niether can 2003 (unicode) be read by earlier version OL, The 2007 & 2003
default data format is the same.
So what did you mean?
