Tim,

Thanks. Providing delegation compatibility through an api is an often requested feature from admins. User in role X will have delegated permissions on some marketing mailbox, etc. The admin triggers this upon staff onboarding and not through the outlook manually for several employees. using ews (deprecated) can work and if you have a direct reference to this specific call that would be appreciated, still it requires to use a different api and having it in the smartermail api would streamline this process.
