I tried to connect with google calendar under General -> Meetings tab.

When I click Click here to sign in with your Google account, it shows Unable to integrate with Google Calendar! tooltips.

I did click Allow integration checkbox on the Google field

I think there is something wrong with Chrome block Google sign-in pop-up windows.

I am able to open the outlook sign-in pop-up windows.

Let me know if I can help with the debug log or more detail. I don't know how to output/have debug log at this moment
