The ability to add an alternate host in the RingCentral Outlook 365 add-on. I can select an alternate host in the desktop app but not the Outlook 365 add-on. When scheduling meetings for my CEO, he sometimes has to leave his 1st group RingCentral call to join a different RingCentral call. When he joins the 2nd call, he disconnects the attendees in the first call because an alternate host can't be select for the first group call. Having this app would be a very nice feature for busy professionals. Please contact me when the feature is available. Thank you. In the meantime, we will use a competitor audio/visual conference tool that meets our needs.
