You need to pass this step in order to complete a migration batch creation. You can also use this line :

Test-MigrationServerAvailability -ExchangeRemoteMove -Autodiscover -EmailAddress emmanuel.demilliere@itfordummies.net -Credentials (Get-Credential -Message 'Onprem Creds')

You need to change the email or the domain name to fit your needs.

Depending on the error you have, you can check other things, hereunder some exemples, this is not a exhaustive list :

You need to run this on your Exchange server on premise.Each test should pass in order to move forward in your troubleshooting.

You can also check at some settings of the Mailbox Replication Service itself :

Both of these should be set to true, if you modify them, you need to run an “IISReset” for them to applied :

Set-WebservicesVirtualDirectory -Identity 'YourServerNameEWS (Default Web Site)' -MRSproxyEnabled:$True -WSSecurityAuthentication:$True

    This helped me find out that it was the Migration Endpoint Associated Administrator account that was locked/expired and therefore made us unable to move mailboxes to Exchange Online.
