部署 Exchange 整合通訊和 Communications Server 2007
  • Unified Messaging server role   Unified Messaging Server 會將 Exchange 2007 與 Communications Server 2007 連線。
  • Hub Transport server role   Hub Transport Server 會將電子郵件從 Unified Messaging Server 路由傳送至使用者信箱。
  • Client Access server role   Client Access Server 主控用戶端通訊協定，例如：郵局通訊協定第 3 版 (POP3)、網際網路訊息存取通訊協定第 4 版 (IMAP4)、安全超文字傳送通訊協定 (HTTPS)、Outlook 無所不在 (舊稱為 RPC over HTTP)、可用性服務及 Autodiscover 服務。Client Access Server 也主控 Exchange Web 服務。
  • Mailbox server role   Mailbox Server 主控使用者信箱。
    如需 Exchange 2007 所含伺服器角色的相關資訊，請參閱概觀。如需如何安裝 Exchange 2007 所含之每個伺服器角色的相關資訊，請參閱新安裝。
  • 雖然您可以將 Unified Messaging server role 與其他 Exchange 2007 伺服器角色安裝在同一台電腦上，但是當您部署 Communications Server 2007 時，建議您將 Unified Messaging server role 安裝在不會執行其他 Exchange 2007 伺服器角色的電腦上。如果在 Unified Messaging server role 的相同電腦上安裝其他伺服器角色，則 Microsoft Exchange 整合通訊服務可能會選取不正確的憑證，而且無法使用相互 TLS 來加密流量。原因是憑證中找到的主體別名有所限制。

    例如，如果您先安裝 Unified Messaging server role，之後再於同一部伺服器上安裝 Client Access server role，則 Microsoft Exchange 整合通訊服務會使用 Client Access server role 所建立的憑證，而不是安裝 Unified Messaging server role 時所建立的憑證。原因是 Microsoft Exchange 整合通訊服務會在信任的根存放區中尋找到期時間最久的憑證。
  • 因為信任的憑證使用相互 TLS 來建立與 Communications Server 2007、Client Access、Hub Transport 和 Unified Messaging Server 的加密通道，所以相互 TLS 交涉期間使用之憑證上的名稱必須符合呈現憑證之伺服器的網域全名 (FQDN)。
