Outlook 2007+ ignores inline style with !important

[horch004]

Hi,

Outlook 2007 and greater ignores inline styles when the style has the !important rule.
See https://www.campaignmonitor.com/blog/email-marketing/2010/05/outlook-2007-and-the-inline-important-declaration/ for a blog about it.

In de CssAttribute class the ToString method explicitly includes the important rule in the output string.
As far I can see a fix would be to not include the rule in the output string.

Since all styles are merged into the inline style property, is there a reason to include the important rule?

I would like to bump this issue. We experience the same problems with Outlook 365.
To me it seems very reasonable to strip the !important declaration when inlining the style attribute.
