Use autodiscover to retrieve additional settings | Autodiscovery may add delays or cause errors depending on DNS/firewall configuration, but it may help in scenarios where a static Server hostname is not possible. |
Use impersonation | Use impersonation to get access to each calendar instead of delegation to the service account. Impersonation usually have higher throttling limits and will be a better option for large installations. It will however need additional permissions in Exchange/Office365. Note: Impersonation requires OAuth login alt. ManagementRoleAssignment with Role:ApplicationImpersonation for the service account. If impersonation is not enabled (Delegation), then Set-ThrottlingPolicy is required. |
