Description

If you upgraded your Microsoft Outlook to version 2016 or you are using Outlook 365 you may encounter this error message when you try to open it. Any of these errors are related to the new AutoDiscovery that Microsoft included in the product to allow Outlook to connect to an active connection, regardless if you are using Exchange or 365. The problem that this is creating around users is that there is no permanent fix for this. If your computer lose connection to the servers when you open Outlook, it will tell you that it cannot find the server and that’s it. You cannot even open Outlook in Offline Mode in order to check your emails and troubleshoot the problem.
