This error can be generated if an index in the on-premises environment is corrupted. try the below.

  1. Rebuild the content index catalog on the on-premises Exchange server. For more information about how to do this, see Reseed the search catalog.

  2. After the index catalog is rebuilt, wait a few minutes until the fast engine starts indexing again.

  3. Determine whether indexing is completed. To do this, run the Get-MailboxDatabaseCopyStatus cmdlet.

    If indexing is completed, the value in the output should show as Healthy.

After indexing is completed, perform the mailbox move request.
