This document covers Internet Service Provider (ISP) / Hosting customer deployments of complimentary products with Enterprise Vault.

Background and Support
ISPs and Hosting environments are highly specialized and it is advised that Symantec Professional Services be involved to create a Solution Design for your implementation. Additionally, ISP and Hosting customers under tight service level agreements (SLAs) with their customers should strongly consider purchasing Business Critical Support, to ensure optimal operations of their Enterprise Vault solution.

Supported Environments
Enterprise Vault is supported in hosting environments with the following Microsoft products:

* Please review current Enterprise Vault "Supported Products list" (found below, in the Related Documents section) for required patch levels of the above products that are approved.

ISP/Hosting customers typically support end user environments utilizing Microsoft Outlook clients communicating at the network level to their hosted (or remote) Exchange, and ultimately hosted Enterprise Vault server. These connections may be native via TCP/IP or over Microsoft Outlook Web Access back-end servers (OWA/IIS). ISP/Hosting customers must provide customer network connectivity for Active Directory permissions for user authentication and administration in all domains archived with Enterprise Vault. Additionally, TCP/IP network connectivity and working domain name service (DNS) servers are required to ensure connectivity exists. Please refer to the Appendix in the Installing Enterprise Vault guide for a list of these ports. Customer and Managed Service Providers (MSP) firewall configurations are not covered in this TechNote. Please refer to the Enterprise Vault Installation and Configuration guide for assistance with TCP/IP network ports that are used.

Hosting customer hardware deployment scenarios as to number of users per server are atypical as those of large enterprise customers thus there is little difference to a large Enterprise Vault customer. It is up to the Hosting customer to implement one of the following approved scenarios with Enterprise Vault, as they are tested and supported configurations.

The following three deployments are recommended and supported at this time by Symantec as Best Practises for Microsoft Exchange Hosting with Enterprise Vault (EV):
