(similar font, same color, same formatting, …) Thunderbird replies to mails using: <blockquote cite="mid:000301c8f32a$c493dda0$4dbb98e0$@dias@inovaprime.com" type="cite"> While Outlook replies them using: <div style=3D'border:none;border-left:solid blue 1.5pt;padding:0cm 0cm = 0cm 4.0pt'> According to MSFT (http://msdn.microsoft.com/en-us/library/aa338201.aspx#Word2007MailHTMLandCSS_Full), Outlook supports the <blockquote> element but not the "type" attribute. On any case, it seems to be "blockquote" definition causing the quoted text to not appear properly. Reproducible: Always Steps to Reproduce: 1. Reply to an email 2. Look at the source of the reply and notice that type="cite" is used 3. Read it in Outlook and confirm the formatting will be wrong Actual Results: Cite formatting is wrong in Outlook. Expected Results: Cite formatting is ok in Outlook.
