Migrated some users from Google's G-Suite Legacy to MS 365.
Used EAC 'Migration batches' for migration of mailboxes (IMAP migration).
In Gmail there are 2 special folders called 'Starred' and 'Important'. They were migrated to MS365 but I cannot delete or rename them in Outlook (both online and in desktop app). I think they are marked as a 'special folder', but I need to be able to delete them as they are not necessary anymore.
Same problem: after a Gmail migration I'm stuck with "Important" and "Starred" folders marked as distinguished and thus cannot be deleted. Also have a funky folder under contacts that looks like a guid that I can't delete.
