Attributes and elements

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

Attributes

Attribute Description
DistinguishedPropertySetId
Defines the well-known property set IDs for extended MAPI properties.

If this attribute is used, the PropertySetId and PropertyTag attributes cannot be used. This attribute must be used with either the PropertyId or PropertyName attribute, and the PropertyType attribute.

The DistinguishedPropertySetId Attribute table later in this topic lists the possible values for this attribute.

This attribute is optional.
PropertySetId
Identifies a MAPI extended property set or namespace by its identifying GUID.

If this attribute is used, the DistinguishedPropertySetId and PropertyTag attribute cannot be used. This attribute must be used with either the PropertyId or PropertyName attribute, and the PropertyType attribute.

This attribute is optional.
PropertyTag
Identifies the property tag without the type part of the tag. The PropertyTag can be represented as either a hexadecimal or a short integer.

The range between 0x8000 and 0xFFFE represents the custom range of properties. When a mailbox database encounters a custom property for the first time, it assigns that custom property a property tag within the custom property range of 0x8000-0xFFFE. A given custom property tag will most likely differ across databases. Therefore, a custom property request by property tag can return different properties on different databases. The use of the PropertyTag attribute is prohibited for custom properties. Instead, use the PropertySetId attribute and the PropertyName or PropertyId attribute.

IMPORTANT: Access any custom property between 0x8000 and 0xFFFE by using the GUID + name/ID. If the PropertyTag attribute is used, the DistinguishedPropertySetId, PropertySetId, PropertyName, and PropertyId attributes cannot be used.

This attribute is optional.

NOTE: You cannot use a property tag attribute for properties within the custom range 0x8000-0xFFFE. You must use a named property in this case.
PropertyName
Identifies an extended property by its name. This property must be coupled with either DistinguishedPropertySetId or PropertySetId.

If this attribute is used, the PropertyId and PropertyTag attributes cannot be used.

This attribute is optional.
PropertyId
Identifies an extended property by its dispatch ID. The dispatch ID can be identified in either decimal or hexadecimal formats. This property must be coupled with either DistinguishedPropertySetId or PropertySetId.

If this attribute is used, the PropertyName and PropertyTag attributes cannot be used.

This attribute is optional.
PropertyType
Represents the property type of a property tag. This corresponds to the least significant word in a property tag.

The PropertyType Attribute table later in this topic contains the possible values for this attribute.

This attribute is required.

DeleteItemField
Represents a delete operation for deleting a given property from an item during an UpdateItem operation.
DeleteFolderField
Represents a delete operation for deleting a given property from a folder during an UpdateFolder call.
AppendToItemField
Identifies data to append to a single property of an item during an UpdateItem operation.
AppendToFolderField
Specifies data to append to a folder property during an UpdateFolder operation.
Exists
Represents a search expression that returns true if the supplied property exists on an item.
FieldURIOrConstant

Remarks

Some attributes cannot be used in combination with other attributes. Any request that comes in with an invalid combination of extended property attributes will generate an error message.

The schema that describes this element is located in the EWS virtual directory of the computer that is running MicrosoftExchange Server 2007 that has the Client Access server role installed.

Note

In Microsoft .NET, a Long is a 64-bit signed integer, while in MAPI and COM, a Long is a 32-bit integer. Most developers will use the Microsoft.NET Framework to develop Exchange Web Services client applications. Therefore, the .NET naming is used instead of the MAPI naming.

For example, the PR_MESSAGE_FLAGS MAPI property, 0x0E07, is a PT_LONG type. In .NET, this is considered an integer. An extended property for PR_MESSAGE_FLAGS is defined as <t:ExtendedFieldURI PropertyTag="0x0E07" PropertyType="Integer"/>.

Example

The following example of a request creates an item that has two custom properties. The first custom property is named IsMyHouse with a Boolean value set to true. The second custom extended property is named HousePrices. It contains an array of Currency values.
