When an email is formatted big and it forces you to scroll side to side, the swipe function to go to the previous email does not work.
Swipe to the next older email does not work when the email is wide enough to force scrolling. Swipe to the next newer email still works though.
When writing an email on the Chrome version of Outlook on my phone, I cannot scroll through the message I've written. It'd be nice to be able to do that. For reference, I'm using a Huawei P20 Pro, accessing through the Chrome browser. I had written an email and could not scroll through the message when the keyboard was open. Closed my keyboard and tried, still couldn't scroll to read it.
