[MS-ASCMD]: ActiveSync Command Reference Protocol Specification

section 2.2.3.156.4. The server checks the value of the key to verify that the value of the
airsync:SyncKey element provided in the request matches a airsync:SyncKey value on the
server. The server MUST provide a Status element (section 2.2.3.152.6) value of 4 if the
airsync:SyncKey value provided in the GetItemEstimate request does not match those expected
within the next Sync command request (section 2.2.2.19.1).
The airsync:SyncKey element value is a string value up to 64 characters in length.
2.2.3.156.4 SyncKey (Sync)
The SyncKey element is a required child element of the Collection element in Sync command
requests and responses that contains a value that is used by the server to mark the synchronization
state of a collection.
All elements referenced in this section are defined in the AirSync namespace.

A synchronization key of value 0 (zero) initializes the synchronization state on the server and causes
a full synchronization of the collection. The server sends a response that includes a new
synchronization key value. The client MUST store this synchronization key value until the client
requires the key value for the next synchronization request for that collection. When the client uses
this synchronization key value to do the next synchronization of the collection, the client sends this
synchronization key value to the server in a Sync request. If the synchronization is successful, the
server responds by sending all objects in the collection. The response includes a new
synchronization key value that the client MUST use on the next synchronization of the collection.
The client MUST store the synchronization key as an opaque string of up to 64 characters.
The client MUST send a synchronization key value of 0 in an initial Sync request and the server
sends a new synchronization key value in its response to the client. The client MUST NOT ignore the
synchronization key value that is included in the initial response from the server.
2.2.3.157 To
The To element is a required child element of the ResolveRecipients element in
ResolveRecipients command requests that specifies one or more recipients to be resolved. The To
element is a required child element of the Response element in ResolveRecipients command
responses that specifies a recipient to be resolved. The To element is an ANR search field. Its value
can be up to 256 characters in length.
All elements referenced in this section are defined in the ResolveRecipients namespace.
