Attributes and Elements

The following sections describe attributes, child elements, and parent elements.

Attributes

Attribute	Description
MaxEntriesReturned	Describes the maximum number of items to return in the response. This attribute is optional.
Offset	Describes the offset from the BasePoint. If BasePoint is equal to Beginning, the offset is positive. If BasePoint is equal to End, the offset is handled as if it were negative. This identifies which item will be the first item delivered in the response. This attribute is required.
BasePoint	Describes whether the page of items will start from the beginning or the end of the set of items that are found by using the search criteria. Seeking from the end always searches backward. This attribute is required.

BasePoint Attribute

Value	Description
Beginning	The paged view starts at the beginning of the found item set.
End	The paged view starts at the end of the found item set.

Child Elements

None.

Parent Elements

Element Description

Element	Description
FindItem	Defines a request to find items in a mailbox. The following is the XPath expression to this element: `/FindItem`

FindItem

Defines a request to find items in a mailbox.

The following is the XPath expression to this element:

/FindItem

Remarks

Seeking from the end involves moving to the origin identified by the offset. Additionally, the pointer is moved back by the number of requested records. For example, if there are 100 records and the offset is 25 from the end, the search starts from 75. If 10 records are returned, the pointer is moved backward an additional 10 records to 65 and returns records 65 through 75. The next index is 64. The next offset from the end for a page is 100 minus 64 which equals 36. 36 is the value for the next offset from the end to get the next indexed page.
