2.2.8 Conversation Actions
Conversation actions are a limited set of actions that a user applies to all E-mail objects, currently in the message store or delivered in the future, that share the same value of the PidTagConversationId property ([MS-OXOMSG] section 2.2.1.2) and thus are part of the same conversation. Unlike rules, as specified in [MS-OXORULE], at most one conversation action applies to any given E-mail object, and conversation actions can be automatically deleted after a period of disuse.
A conversation action is a combination of any of the following actions:
Ignore
Stop Ignoring
Move to Folder
Move to Store
Stop Move
Add Category
Remove Category
Clear All Categories
The client and server SHOULD<21> persist conversation action settings in an FAI message in the conversation actions settings special folder, as specified in [MS-OXOSFLD] section 2.2.5.1. The relevant properties of a conversation action FAI message are enumerated in sections 2.2.8.1 through 2.2.8.10.
