I created a mirror page URL content block and wanted all of the text, including the link, to be gray. The text is gray in every email client that I tested except for Outlook when I view on my desktop (here it's blue). This is the HTML used:
<% if ( document.mode != 'mirror' && document.mode != 'forward' ) { %><p align=center>
<font style="font-family: Arial, Arial; font-size: 12px;">
To view this email as a web page, go
<span style="color: #58595b;"><a style="color: #58595b;" <a href="<%@ include fragment='MirrorPageUrl' %>" _label="Mirror page" _type="mirrorPage">here.</span></a>
</font>
</p><% } %>
Any ideas on why the link is blue in Outlook?
