A rich set of single-value and multivalued data types is provided for item properties in the Exchange store. The following table lists these types, using the XML-data representation for each one. The second table lists the mappings between these data types and the types presented using OLE DB and MAPI.
| Types (XML) | Description |
|---|---|
| Boolean | A Boolean value, either True or False. In an XML string, this value is either "1" for True or "0" for False. |
| i2, mv.i2 | 2-byte integer. |
| int, mv.int | 4-byte integer. |
| i8, mv.i8 | 8-byte integer. |
| dateTime.tz, mv.dateTime.tz | Date and time. |
| r4, mv.r4 | 4-byte floating-point number. |
| fixed.14.4, mv.fixed.14.4 | Fixed floating-point number. |
| float, mv.float | Floating-point number. |
| uri | Uniform Resource Identifier in string format. |
| uuid, mv.uuid | GUID in string format. |
| string, mv.string | 2-byte character string (Unicode). |
| bin.base64 mv.bin.base64 | Binary data (base 64-encoded). |
