3.1.4.3 Marking a Conversation as Read or Unread

When a conversation is marked as read or unread, all e-mail messages that are in the conversation and that are in the current folder are marked as such.

To mark a conversation as read, the client sends a Sync command request ([MS-ASCMD] section 2.2.1.21) that contains an airsync:Change element for each item in the conversation and in the current folder, as specified in [MS-ASCMD] section 2.2.3.24.

To mark a conversation as unread, the client sends a Sync command request ([MS-ASCMD] section 2.2.1.21) that contains an airsync:Change element for at least one item in the conversation and in the current folder, as specified in [MS-ASCMD] section 2.2.3.24.
