It turned out to be an issue for the ISP and they have been advised. It just
so happened it coincided with me loading outlook 2007, hence my confusion.

Thanks for suggestion.

Since my original post I have established that if I am replying to an
email,
from the same person that this goes through OK.

I sent a message using outlook express and when I had a reply I used
Outlook
to read it and then replied - it went through.
