Description

Protocol (POX)

Contains the specifications for connecting a client to the computer that is running Microsoft Exchange Server 2007 that has the Client Access server role installed.

If the e-mail client does not match the network requirements, it should try other protocol types. ISPs may provide one set of servers with Protocol (POX) tags that do not require authentication but are required to be on the ISP network. ISPs may list another set of servers that require authentication but are not required to be on a specific network.

The NetworkRequirements element is optional.
