This generates an error message.Īfter you upgrade Outlook or you create a new profile, Autodiscover is required to configure an Outlook profile the first time that Outlook is started. If you select Install anyway to upgrade to Office 2016, and then you start Outlook, Outlook may be unable to connect to the Exchange Server Autodiscover service because Autodiscover is not configured or is not working correctly.

The update process checks your current Outlook configuration to determine whether you are affected by some known issues. You receive the error messages that are mentioned in the Symptoms section if the Office 2016 update process determines that the Autodiscover service is inaccessible. Outlook may freeze at the splash screen for several minutes before these errors messages are displayed.
