We are getting this error (Calendars.Read permission is missing. Please check if permission is assigned to the application and/or Sign In). Calendar.Read permissions are set we have waited the 5 min for the settings to propagate and still after 5 min it doesn't seem to connect. Any ideas?

Got the same issue...confirmed everything is setup correctly several times and even expanded access to read/write for both Microsoft Graph and Exchange and still a no go.

NVM, figured it out per another thread on same issue. Make sure you set the permissions for applications and not delegation. That is the issue.

Yes, I found that was the problem too!
