Sadly we have to deal with people who don’t know how to save in any other format than the defaults their M$-Office provides (including emails only readable with Outlook or extensions). So better compatibility while importing M$ saves users of LO a lot of time, even if they don’t intend to use M$ themselves.
I often ask myself, why do people use LO to convert a bunch of M$-Office files to .pdf Shouldn’t they ask at M$ or Adobe for this ?
