Email Template trick: max-width with outlook

max_width_email.html

<!--[if mso]>
 <center>
 <table><tr><td width="580">
<![endif]-->
 <div style="max-width:580px; margin:0 auto;">
 
 <p>This text will be centered and constrained to 580 pixels even on Outlook which does not support max-width CSS</p>
 
 </div>
<!--[if mso]>
 </td></tr></table>
 </center>
<![endif]--> 

You're the real MVP 🤗

Isn't better use table and td?

love it, thanks @elidickinson

still works after 8 years

Great solutions everyone! Although none of them can stand the normal text mixed with super long words (or just text with no spaces). Windows Mail/Outlook (2007, 2010, 365) keep stretching the table...
NB: break-all and hyphens wouldn't help since the first will break normal words, and the later will brake the links.

@philipp-klinz Great job this works perfectly to center object without center text.
If someone want to center object and text, simply use style="text-align:center;.
