HTML Rendering Differences Between New and Classic Outlook

Question

Hi Team,

The HTML table formatting, including alignment and column width, is displayed differently in the new Outlook compared to the classic version. Styles such as text alignment, column spacing, and table layout are not preserved as expected, leading to inconsistencies in email rendering. This issue affects the readability and structure of the content when viewed in different versions of Outlook.

Regards,

Hi Alex,

Based on the description, the HTML table formatting, including alignment and column width, is displayed differently in the new Outlook compared to the classic version.  HTML rendering inconsistencies between the new and classic Outlook versions are a common challenge due to differences in their underlying rendering engines.

You have a statement not a question. But it is a real lissue.

The _reason_ is because Outlook Classic uses Microsoft Word's HTML renderer and New Outlook uses up to date web browsers (Chromium?).
