[MS-ASCMD]: ActiveSync Command Reference Protocol Specification

2.2.2.3.2 Response
The following code shows the XSD [XMLSCHEMA1] for the FolderDelete command response.
2.2.2.4 FolderSync
The FolderSync command synchronizes the collection hierarchy but does not synchronize the items
in the collections themselves.
This command works similarly to the Sync command (section 2.2.2.19). An initial FolderSync
command with a SyncKey element (section 2.2.3.156.2) value of 0 (zero) is required in order to
obtain the list of folders and the synchronization key associated with that list. The synchronization
key MUST be returned in the SyncKey element of the response. This synchronization key MUST be
used in subsequent FolderSync commands to obtain folder hierarchy changes.
Unlike a Sync request (section 2.2.2.19.1), there is no GetChanges element (section 2.2.3.72)
submitted in the FolderSync request (section 2.2.2.4.1) to get changes from the server. All folders
MUST be returned to the client when initial folder synchronization is done with a synchronization key
of 0 (zero).
The FolderHierarchy namespace is the primary namespace for this section. Elements referenced in
this section that are not defined in the FolderHierarchy namespace use the namespace prefixes
defined in section 2.2.1.
The following table lists the elements that are used in FolderSync command requests and
responses.
