In other systems, we are still required to use HTML4 Transitional, and Outlook is only part of the problem. Even webmail, which you expect to handle modern HTML, just fails on unexpected ways (no CSS on head, even if it's embedded on the mail, is one of those egregious problems). It's miles better to be the one working on the website than the marketing email.
- if you copy and paste stuff from Office a lot (like Office users tend to do) it's nice that the formatting will be consistent
- being feature-rich can be a bug and not a feature when dealing with marketing emails
Didn't crash but became very unstable/laggy & 'not responding' faded out for a few seconds.
No issues on the Outlook app on iOS or webmail on Edge though.
They always look so familiar with my own edge-case programming hiccups.
My wild guess is a null character was introduced into ubers' e-receipt. Would be fun to investigate.
