Prevent Outlook from wrapping text in messages

How can I prevent Outlook from wrapping the text in my messages?

For example, if I save a draft of an email, when I open it up again, line breaks have been inserted.

I have options set to UTF-8.

enter image description here


file->Options-> Mail

in the 'Message format' block: Automatically warp text at character->132

Default is 76 and is quite alright

you cannot remove it or make it longer than 132... (Outlook mail Format)
