I am trying to raise awareness for this issue. If you are a RingCentral user (Office@Hand users can't vote), please go vote (and get your users to vote) for the idea (feature request) at the following link: https://ideas.ringcentral.com/ideas/CUSTCOM-I-2557
I am an AT&T Office@Hand customer, but I believe the desktop application is similar to what RingCentral users use for video meetings. The application only shows calendar events from connected Microsoft or Google accounts. It does not keep track of its own upcoming scheduled meetings. This is a severe limitation when compared to other video conferencing solutions, such as GoToMeeting, which shows upcoming and past meetings inside the desktop application. The Office@Hand/RingCentral desktop applications need to be aware of AT LEAST upcoming scheduled meetings. I believe this is a feature that is sorely needed.
