When we distribute onboarding invitation e-mails via Auth0 Organizations, they fail to render correctly in Outlook for Windows. They do, however, render correctly in Outlook Web Access.
Given that the majority of our target user base will be using Outlook for Windows, it would be nice if this could be addressed, assuming the fault isn’t something on our side.
(For interest, when we had similar issues with our own HTML e-mail newsletter, we wound up having to use table elements a great deal and generally write less CSS.)
Email layout is wrong in Outlook for Windows / desktop client compared to Outlook for Web
We would recommend customising your invitation email template’s HTML using the tips mentioned in that blog and community thread in a development environment tenant, and testing with Outlook for Windows to see if it improves the rendering.
