Graham,

Thank you so much for your help on this I have now managed to get all of my email attachments downloaded and with only the latest version of each type.

So you know the numbers; I started with all emails from 2007, which in the end I had 24,826.

Within these emails there were 89,514 attachments in total.

Because of your help I can now delete all of the archived emails and I am left with 4,503 as of this morning!
