The login service has been fully restored for Service Providers, MSPs, and Domain Administrators as of 10AM.
The user access has also been restored but it's sluggish due to everyone authenticating/reauthenticating at once, we expect the sluggishness to last 10-15 minutes at which point all the login functionality will resume normal operation.
Update 01/12/2024 14:54 PM 14 days
ExchangeDefender admin web services have had issues with user login this morning. The root cause is with the authentication (login) server and it has been addressed.
We are returning the service to normal operations, please stand by.
