Undisclosed recipient - address order

[roblea]

Hi
I know how to set up an undisclosed recipient folder in outlook express, but I can't find out how to put the e-mail addresses (within this folder) into alphabetical order. The reason I need to this is that the address list contains thousands of addresses and I am keen to avoid repetition (when the same address has been entered more than once). If I could arrange the undisclosed addresses in order, then repeat entries would be immediately obvious and I would be able to delete them.

I have found a way of ordering a list (of e-mail addresses in Microsoft word), but I cannot then drag and drop the list of addresses into the undisclosed recipient folder.

Any suggestions welcomed.

Many thanks in advance, Rob LEA
