Outlook 2007 HTML and CSS Validator 1.0

Outlook 2007 HTML and CSS Validator by Microsoft

Outlook 2007 HTML and CSS Validator is a purpose-built tool that helps email designers and developers create HTML emails that render consistently in Microsoft Office Outlook 2007. Because Outlook 2007 uses Microsoft Word’s rendering engine, many modern HTML and CSS features are not supported. This validator scans your markup, identifies unsupported or risky patterns, and recommends safe, email-tested alternatives.

Key features:

• Outlook 2007–specific ruleset: Flags unsupported properties (such as floats, position, and background images), non-inline styles, and complex layouts that won’t render as intended.
• Actionable guidance: Provides clear explanations and suggested fixes, including code examples for common patterns like buttons, columns, and background treatments.
• Inline CSS analysis: Checks and prioritizes inline styles, helping you avoid external or embedded CSS that Outlook 2007 may ignore.
• Detailed reports: Generates line-referenced findings with severity levels and summaries you can share with designers, developers, and QA.
• Flexible input: Validate pasted code, local files, or URLs; run single checks or batch validations for large campaigns.
• Workflow integration: Optional command-line and CI support to catch issues before emails go to staging or production.

Ideal for marketing teams, front-end developers, and QA specialists, Outlook 2007 HTML and CSS Validator reduces rendering surprises, shortens review cycles, and helps ensure brand consistency across one of the most challenging email clients.
