[Blind-sysadmins] office 365 groups and Outlook 2016

Hello all, Was wondering whether anybody knows how to do this? My group has a couple of Office 365 groups, and I've gotten them to display in Outlook 2016, though I can't seem to figure out how to do liking and disliking, nor how to expand messages. I can do these functions just fine, though, via Android, just not in Outlook. The Office 365 support folks say that there is a way to do it via the Outlook desktop client, though. If anyone knows it, that'd be great. Thanks guys.
