1.3 Overview
This protocol consists of a set of XML-based commands that are used by a client device to
synchronize and exchange its e-mail, files, and data with a server.
The client first uses the Autodiscover command (section 2.2.2.1) to get a user's account
configuration. The client can then view and modify server data related to that account, including e-
mail messages and attachments, folders, contacts, and calendar requests.
The client then uses the Provision command (section 2.2.2.12) to send device information to the
server and to get and subsequently acknowledge security policy settings from the server. Next, the
client uses the FolderSync command (section 2.2.2.4) to retrieve the folder hierarchy of the user.
Next, the client typically uses the GetItemEstimate command (section 2.2.2.7) to retrieve the
number of changes that need to be downloaded to the client via the first Sync command (section
2.2.2.19) request. This is immediately followed by the Sync command, to get a synchronization key
and then messages from the server. Optionally, the Ping command (section 2.2.2.11) or hanging
Sync command can then be issued to keep the device up-to-date on any server changes.
The client processes outgoing e-mail using the SendMail (section 2.2.2.15), SmartReply (section
2.2.2.18), and SmartForward (section 2.2.2.17) commands. For incoming messages, the client can
call the ItemOperations command (section 2.2.2.8) to fetch the message, and then use the
MoveItems command (section 2.2.2.10). S/MIME messages are processed with the
ResolveRecipients (section 2.2.2.13) and ValidateCert (section 2.2.2.20) commands.
The client uses the FolderSync, FolderCreate (section 2.2.2.2), FolderUpdate (section 2.2.2.5),
and FolderDelete (section 2.2.2.3) commands to update, create, and delete mailbox folders on
the server.
For meeting requests, the client uses the MeetingResponse command (section 2.2.2.9).
The client can set and request server parameters by using the Settings command (section
2.2.2.16).
The client uses the Search command (section 2.2.2.14) to find particular items on the server.
