22.214.171.124 Retention and Archive Properties
Retention and archive properties specify information about the retention policy or archive policy. These properties are valid on e-mail Message objects. Some of these properties are also valid on folders. The retention policy and the archive policy are independent features. The server can enable one of these policies, both of these policies, or neither of them. For details about how the retention policy and archive policy settings are communicated between client and server, see [MS-OXOCFG] section 126.96.36.199.3.
