Login with AzureAD Account sync instantly goes in "Error" state

I got the same behavior. It seems to come from my firewall with inspection ssl.

I asked urls exception with the feedback button but I didn't get any answer yet.

When I whitelisted a lot Microsoft URL (specially link to azure), everything was looking better.

We need an online dashboard to see which data are saved (date last sync) and able to clear them as well.

I think that a personal Microsoft account has a dashboard.
