Publishing Exchange Web Service in Autodiscovery Service

MigrationWiz will attempt to discovery your Exchange Server using the Autodiscovery Service if you publish the end-point.

By default, Exchange Server 2007 does publish the external URL to your Exchange Web Service as apart of the Autodiscovery Service. Furthermore, there is no user interface to configure this setting either. So you are stuck configuring it manually using Powershell.

To publish your Exchange Web Service URL, open the Exchange Management Shell and run the following command on your Client Access Server (CAS):

Set-WebServicesVirtualDirectory -Identity “EWS (Default Web Site)” -ExternalUrl “https://mail.contoso.com/EWS/Exchange.asmx” -BasicAuthentication:$True

So when you attempt to migrate Exchange to Exchange Online using MigrationWiz, we’ll detect your settings properly.
