Enhanced performance, designed for simplicity – the new Outlook for Mac

@Jessica_Wilczek 

Currently I use the setting "Reading Pane - Below". All of the examples of the new Outlook that I have seen show Reading Pane - Right.   If "Below" is unavailable in the new Outlook, it will be a show-stopper. And it needs to be possible to choose which columns to display, the order in which to display them, and their widths.

I could toggle to the new version and find out. However, nothing I have seen so far asserts, positively, that one can toggle back and forth with no loss of anything at all. It's implied, perhaps, but that's not good enough. In particular, I have a large volume of emails saved "On My Computer", and from what I've read, the new Outlook doesn't support "On My Computer". This essential feature is evidently not available yet. I cannot afford to lose them.

And as is the case for many others, IMAP and iCloud email are essential.
