Email not accessible on any platform after "migration"
Since last Monday, 11.13.17, no one in our company has been able to access email via any method. Mobile devices, webmail, Outlook, all no longer able to access. We can log into the business portal but no longer have access to the links that used to bring us to the OWA interface. We've got a ticket filed with Teir 2 support but no one will call us back. No one answers the phone at the Cloud Services support and then it goes to a voicemial box which is full.
