I am successfully merging addresses from a Contact List into a document in
Word. Outlook 03, Word 03. The issue is that on some addresses I get an
extra line eg:

Mr Jones
London House
13 London Road

London
SW1

I have checked the address format in the contacts list and it is exactly the
same as those that work no problem. I am using the - Address Block -
function in Mail Merge in Word to provide me with the address format.
