This drove me crazy for a while, because I couldn’t find the option to hide the stage in a Skype for Business conversation once I no longer wanted to see what someone was presenting on their screen – might not happen very often, but it happened enough to want to hunt it down, and it’s not as intuitive as I’d think it would be. Honestly, I expected the option to be a bit more straightforward, like maybe at the top of the screen right beside Request Control? I’d even settle for it being behind the ellipse (…) on the bottom right, but no…
To hide the stage, click the sharing button, then Hide Stage:
Simple, right? Just as simple as clicking File – Open – Import in Outlook 2010 to actually export a file!
Sigh… hope this helps someone else who’s been wondering where that dang “hide stage” button is!
