There is no drop-in fix for <textarea> in Outlook Classic. Design so the email still reads without it.

Caveats (3)
- 1. Outlook Android, Yahoo Mail Android, Samsung Mail, Proton Mail: Buggy. A number of android clients will not show the keyboard when the input is clicked. Copy and pasting text works.
- 2. Apple Mail iOS: Buggy. Screen jumps when input is in focus.
- 3. Thunderbird: Buggy. Interacting with the element submits the form it belongs in.
Caveats as recorded by caniemail (MIT), one entry per wording.
