The following table describes permitted editing methods of Exchange Online schema types and names restrictions required by system object processing.
Adding and deleting user mailboxes can only be done in One Identity Manager through assignment subscriptions in Microsoft Entra ID. This creates a mailbox that does not appear in the database until it has been synchronized. Afterward, it can be provisioned automatically in Exchange Online.
