Windows 11 mail app html messages not always displaying
I'm running Windows 11 on my PC (Dell XPS 8930) and using the built-in mail app. Everything is updated to current versions.
Some HTML messages just display the HTML in the code, others display a blank screen, and some are displayed fine.
When I go to the ATT/Yahoo web interface, everything displays fine.
I have an S21 Ultra phone with Outlook Mobile (with current updates) that always works fine.
FYI, I recently had issues downloading all the messages in Windows 11 mail app. It randomly would not download any messages for a few hours. Eventually it would start again, but all the messages during that time frame never showed up. Eventually, I fixed it by uninstalling/reinstalling the Mail and Calendar after doing reset, repair, sfc, DISM, etc.
How do I get it to work? From what I can find, Windows Mail after Windows 8 is OAuth.
