[Blind-sysadmins] New Outlook on the Web and questions regarding NVDA and JAWS

Hi all, In light of recent projects, I've had the opportunity to try out Outlook on the Web. I find it works ... somewhat,, but I did notice a few unlabeled buttons. I find sending emails very difficult, and then trying to switch between portions of the interface very inconvenient at best, impossible at worst when frames don't let screen readers go. I'll be glad though to report that behavior from JAWS and NVDA are the same. What do you all say?
