I (like others) support Outlook Mac for a decent size community. We have a lot of OS switchers who complain about the lack of side-by-side view. I've submitted the feedback years back to Microsoft, and I hope it's included in the next release. Calendaring is an important part of what people use Outlook for. It'd be great to hear if that's going to be included in the next version so we can do a little marketing before the release.
