We are now into August, and this is still an issue. Agree with others, this is quite embarrassing and annoying. I also agree with others here that we lost so many functionalities with this "New" version of Outlook. This is just one example of something that I have to switch over to the old version to do (if I remember to do this before hitting send on a meeting with many attendees, including high level executives). It just seems like the new version was rolled out way to soon without testing all of the functionalities that we all have been accustomed to in the old version.
