2.2.2.18 SmartReply
The SmartReply command is used by clients to reply to messages without retrieving the full,
original message from the server.
Clients SHOULD NOT save messages directly to the local Sent Items folder; instead, clients SHOULD
use the SaveInSentItems element (section 2.2.3.134) to automatically save the messages on the
server. It is not possible to reconcile the local Sent Items folder with the server's Sent Items folder
by using the Sync command (section 2.2.2.19). Items in the server's Sent Items folder can be
added to the client by using the Sync command, but it is not possible to add items that are in the
local Sent Items folder to the server.
The SmartReply command can be applied to a meeting. When SmartReply is applied to a
recurring meeting, the InstanceId element (section 2.2.3.78.2) specifies the ID of a particular
occurrence in the recurring meeting. If SmartReply is applied to a recurring meeting and the
InstanceId element is absent, the server SHOULD reply for the entire recurring meeting. If the
value of the InstanceId element is invalid, the server responds with Status element (section
2.2.3.152.15) value 104, as specified in section 2.2.4.
The SmartReply command is similar to the SendMail command (section 2.2.2.15), except that the
outgoing message identifies the item being replied to and includes the text of the new message. The
full text of the original message is retrieved and sent by the server. Using the server copy of the
original message saves network bandwidth by not downloading the original message to the client
and then uploading it again with the reply.
The SmartReply command lists the message recipients, so it is used to implement both Reply and
Reply-to-All functionality. It is the responsibility of the client to implement Reply and Reply-to-All
functionality.
By default, because the original message and the reply messages can use different character sets
(2), this command will always send the outgoing message by using the UTF-8 character set (2) for
the body of the message.
The ComposeMail namespace is the primary namespace for this section. Elements referenced in
this section that are not defined in the ComposeMail namespace use the namespace prefixes
defined in section 2.2.1.
The following table lists the elements that are used in SmartReply command requests and
responses.
