We use the Outlook Calendar app for leads to book demos. There has been issues over the last few months where sometimes it will work (show availability for the sales team on a round-robin basis) and other times, it will not work (show that there is no availability). There has always been availability across the team, we’ve checked that everyone has the right settings, availability and that our calendars are still connected but we still have the issue. I’ve tested in incognito mode, on a different device, on a different browser and sometimes it works, sometimes it doesn’t. 

Has anyone else had this issue and managed to fix it permanently?
