When migrating to or from Microsoft Office 365, you should use the default settings in CloudM Migrate. Generally, the EWS URL should only be specified in scenarios where auto discovery cannot be used.
Problem
A common problem when migrating from Exchange 2007 upwards is to determine the correct EWS URL. The default URL for EWS looks something like: https://mail.domain.com/EWS/Exchange.asmx
Solution
If using the above URL with the appropriate domain is not functional, the correct URL can be retrieved via the Exchange admin.
The Exchange admin can obtain the URL via a PowerShell command on the exchange server
- Open PowerShell on the Exchange server.
- Type Get-WebServicesVirtualDirectory |Select name, *url* | fl.
- The URL will be provided.
