What does the DeploymentPro error: "ERROR: Failed to retrieve Exchange Online server name" mean?
DeploymentPro tries to create a new Outlook profile, it uses the
admin credentials you provided in your MigrationWiz project to query Exchange Online for the server name of that mailbox.
If you get the error that you failed to retrieve the Exchange Online server name, verify that
the admin credentials you provided in your MigrationWiz project are
correct and have Global Administrator privileges in Office 365.
