[MS-ASCMD]: ActiveSync Command Reference Protocol Specification

The Fetch element cannot be used to get truncated calendar, contact, recipient information, or task
items from the server.
2.2.3.61 FilterType
The FilterType element is used in the following command requests:
•GetItemEstimate command requests (section 2.2.2.7.1)
•Sync command requests (section 2.2.2.19.1)
The definition of the FilterType element differs according to the context in which it is used. For
more details, see section 2.2.3.61.1 and section 2.2.3.61.2.
2.2.3.61.1 FilterType (GetItemEstimate)
The airsync:FilterType element is an optional child element of the airsync:Options element and
the Collection element in GetItemEstimate command requests. In both contexts, it specifies a
time window for the objects sent from the server to the client.
Elements referenced in this section are defined in the GetItemEstimate namespace, except where
otherwise indicated by the presence of a namespace prefix (as defined in section 2.2.1).

The airsync:FilterType element applies to e-mail, calendar, and task collections. If a filter type is
specified, then the server sends an estimate of the items within the filter specifications.
If the airsync:FilterType element is present in the request, then the server manages objects on
the client to maintain the specified time window. New objects are added to the client when they are
within the time window. If the airsync:FilterType element is omitted, then all objects are sent
from the server.
Calendar items that are in the future or that have recurrence, but no end date, are sent to the client
regardless of the airsync:FilterType element value.
The airsync:FilterType element does not support contact collections. However, if the
airsync:FilterType element is included in a GetItemEstimate request for a contact collection, no
error is returned.
The valid values for each collections type are listed in the following table.
