Is this a known issue today? I can't access anything Microsoft which includes the admin portals and view to see if there is an ongoing issue?

Does anyone else have this today?

Thanks in advance! also Microsoft - not helpful that I can't contact anyone or get to any status page that means something to us.

    On our Azure AD sync server all services were running that should be. I found a service called:

    "Microsoft Online Services Sign-in Assistant"

    Description - "Enables authentication to online Microsoft services"

    I restarted this service and then was able to login straight away online again.

    I hope this helps anyone else caught by this error.

    Might just be us! just had an email after looking into this for an hour: " You’re receiving this email because we have detected a critical alert on one of your AadSyncService instances."

    Going to look at our Azure sync server now.
