Outlook Email Broken Layout Fix: Resolve Default Image Blocking Layouts for Financial Services & Banking
Financial emails carry high-compliance requirements. Layout collapses, overlapping text, or accessibility failures can lead to compliance audits and client confusion. Below is the targeted integration guide to fix Default Image Blocking Layouts inside Outlook 2016 templates when using React Email.
Technical Breakdown
Outlook 2016 uses the Microsoft Word (MSO) which lacks support for standard rendering rules. This causes Default Image Blocking Layouts elements to break or collapse when rendering templates.
React Email Behaviors
React Email relies on compiling CSS parameters dynamically. However, React Email's compiler cannot parse raw MSO conditional comments or VML structures in TSX files directly. Enforce strict WCAG color contrast standards across your statement tables and summary grids to ensure legibility and regulatory compliance.
Remediation Code Block
To resolve this, always define explicit width and height attributes on your images to preserve their layout boxes when blocked. Add robust alternative (ALT) text styled with CSS font-sizes and colors, and encode vital brand logos directly as Base64 data URIs. In your React Email campaign manager, make sure you configure your links to run via {unsubscribeUrl}.

How to Deploy inside React Email
Copy the fixed VML or table wrapper code block from the remediation box above.
Import the standard '<Html>' or '<Container>' primitives. To insert our VML or custom Outlook table markup directly, wrap the raw HTML snippet inside React's 'dangerouslySetInnerHTML' parameter on a div or span.
