- If the organizer's mailbox no longer exists on the source or cannot be accessed for some reason, then CloudMigrator cannot access the acceptance status info and therefore will not migrate them
Exchange/Office 365 destination
When Exchange/Office 365 is the destination, you'll see the setting 'Migrate Non-Organizer Attendee Statuses'. When enabled, CloudMigrator will attempt to migrate attendee statuses for appointments where the migrating user is not the owner (when the owner is being migrated attendee statuses are always preserved). Due to API limitations, for any appointments from outside of the domain and from any accounts that no longer exist the attendee status will never be migrated.
