Symptoms
In Microsoft Skype for Business 2016, you try to select presenters for a Skype meeting by clicking Meeting Options > Choose presenters. When all members are moved from attendees to presenters or vice versa, the Meeting Options Presenters dialog box loses the focus and the Tab key on the keyboard can't be used to move control.
Resolution
To fix this issue, install the August 7, 2018, update (KB4032255) for Skype for Business 2016.
