Hi @andrewjo5,
Here are some steps that can help you to solve the issue.
Simplify the Email Design: Avoid using complex CSS, especially those not supported by Outlook, such as floats, background images, or certain padding/margin settings. Stick to basic HTML and inline styles.
Use Tables for Layout: Outlook handles table-based layouts better than div-based ones. Structure your email using tables, and ensure they're properly nested.
Test in Litmus or Email on Acid: Use tools like Litmus or Email on Acid to test your emails specifically in different versions of Outlook.
Conditional Comments: Use conditional comments to target specific versions of Outlook and apply fixes as needed.
Hope this helps!
Regards,
Celia
