I recently noticed a spout of emails coming into my inbox that have background images!? As many developers know background images in outlook are non existant, unheard of, a miricle!
So as any self respecting developer would do i jumped straight onto google with the string of keywords "when did outlook start supporting background images". Well, as it turns out a backround *image* does work, its background *images* that do not.
I came accross a blog that then explains that background images do not work in Outlook (thank goodness im not going crazy!) - but what will work is one single background image that sits in the body tag! There is one little snag that you will need to deal with (as if a Microsoft product would just work!). While every other client seems to gracefully assume no-repeat for the second part of the repeat line, Outlook does not. Take a look at the css code below and boom, you'll have body background images working.
