REF: E14 Mailbox Role – Part 1 - Overview

-

 

 

Mailbox servers perform the following functions:
  • Host mailbox databases
  • Provide e-mail storage
  • Host public folder databases
  • Calculate e-mail address policies
  • Generate address lists and offline address books
  • Conduct multi-mailbox searches
  • High Availability and Site Resiliency
  • Content Indexing
  • Messaging Records Management and Retention Policies

Mailbox Server Interactions
  • The Mailbox server accesses recipient, server, and organization configuration information from Active Directory.
  • The Store driver on the Hub Transport server places messages from the transport pipeline into the appropriate mailbox. The Store driver on the Hub Transport server also adds messages from the Outbox of a sender on the Mailbox server to the transport pipeline.
  • The Client Access server sends requests from clients to the Mailbox server, and returns data from the Mailbox server to the clients. The Client Access server also accesses offline address book files on the Mailbox server through NetBIOS file sharing. The types of data that the Client Access server sends between the client and the Mailbox server are messages, free/busy data, client profile settings, and offline address book data.
  • The Unified Messaging server retrieves e-mail and voice mail messages and calendar information from the Mailbox server for Outlook Voice Access. The Unified Messaging server also retrieves storage quota information from the Mailbox server.
  • Outlook clients that are inside your firewall can access a Mailbox server directly to send and retrieve messages. Outlook clients outside the firewall can access a Mailbox server using remote procedure call (RPC) over Hypertext Transfer Protocol (HTTP).
