After migrating to Gsuite/Gmelius 5 days ago, the migration has finally finished. Unfortunately our email address has ever received is marked as Unassigned. As these are emails from the past 2 years, is there a way to bulk-close these emails? Selecting all 100 mails on a page marking them as closed takes forever and it is clear that it is too much to handle for Gmelius.
Could anyone provide help?
