I can't find anyone talking about this anywhere, but I'm having an issue creating a responsive HTML email where Outlook mobile is hyphenating words and I can't switch off the hyphenation with CSS, despite my best efforts.

Here's the code I'm using, trying every CSS trick for removing hyphenation I can find:

<p mc:edit="article_body" style="
        margin:0;
        padding:0;
        margin-bottom:10px;
        color:#0a0a0a;
        font-family:Helvetica,Arial,sans-serif;
        font-size:16px;
        font-weight:400;
        line-height:1.5;
        text-align:left;
        -moz-hyphens:none;
        -ms-hyphens:none;
        -webkit-hyphens:none;
        hyphens:none;
        word-wrap:normal;
        word-break:keep-all;">
            Ut labore et dolore magna aliqua. Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo consequat nulla pariatur. Ut enim ad minim veniam, quis nostrud exercitation.
    </p>

When displayed in a narrow, mobile layout on Outlook for iOS, the app still forces hyphens into the content, despite the CSS.

Does anyone know how to prevent hyphens in Outlook mobile, or if it's impossible? I don't mind the hyphens personally, but the client is asking if we can get rid of them.

As you can see it's a mailchimp template so I can't really use any hacks inline with the content.

Thanks
