We are in the process of migrating from Google Workspace (Gmail) to Exchange Online and we have migrated about 40 users so far but we keep getting the following error on all the remaining migration batches.
We don't have an on premise Exchange Server, we are migrating to O365
I have deleted the batches that have caused the issue and created new ones with less users in the .csv and also on some of them even just created one user per batch but to no avail. Always getting the below error.
Should I create a new Google service account or does anyone have any other suggestions. It was working fine and then suddenly just stopped.....
We have made no changes to our environment or anything. The firewall is not complaining about anything.
We only have about 60 more users to do...

    Hi @Rachel Coles

    Please check the result running below command on your Exchange online server side. Test-MigrationServerAvailability is used to test the availability of the target server in preparation to perform cross-forest mailbox moves, include migration of mailbox data from an IMAP server to Exchange Online mailboxes.

    $MRSEndpoints = (Get-MigrationEndpoint).Identity  
    Foreach ($MEP in $MRSEndpoints) {Test-MigrationServerAvailability -Endpoint $MEP}  
    

    To Create endpoint-

    $Credentials = Get-Credential  
    New-MigrationEndpoint -Name Endpoint -Gmail -RemoteServer MRSServer.contoso.com -Credentials $Credentials  
    

    And if you are not familiar with how to Connect to Exchange Online PowerShell, please refer to the steps introduced in this official document.

    Hi All,

    We have opened a case with Microsoft as they were throttling the EWS and they mentioned permission but we will see.
    I will keep you all updated on what is the outcome
