    Run the below command to remove the mailbox from the first migration batch in the list:

    Remove-MigrationUser -Identity <MailboxIdentity> -BatchId 'FirstBatch'

    Repeat this step for each migration batch that the mailbox is in.

    Once you have removed the mailbox from all migration jobs, you can try migrating it again.
