Unfortunately my colleague is not quite correct. There are two ways to make this a "sticky" experience.
1) You can just always go directly to "http://basic.webmail.aol.com"
2) You can click on "Accessible version" - this makes it sticky. This version is the same as "Basic" - but it will also turn off the Rich Text Editor (which you can enable in settings again).
I recommend using option 1.
