We are currently investigating an ongoing event within our system, that is limiting access to the HostedExchange 2016 control panel for a large portion of our customers.
When navigating in SiteControl, upon clicking on "MS Exchange 2016" customers are not able to proceed to the Exchange management portal.
The functionality of e-mail services is not impaired.
11:32 AM EST: The main cause has been identified and the issue has been resolved. We continue to monitor the platform.
