MORE INFORMATION

Collaboration Data Objects (1.1, 1.2, 1.21)

To retrieve the property using Collaboration Data Objects (1.1, 1.2, 1.21) (formerly known as Active Messaging), use the Fields collection of the AddressEntry property on the Recipient object. Here is the syntax:

objRecip.AddressEntry.Fields(&H########).Value

For example, the following code displays the value of Custom Attribute 7 in a message box. (This code assumes the variable objRecip points to a resolved Recipient object on Microsoft Exchange Server.) 
MsgBox objRecip.AddressEntry.Fields(&H8033001E).Value
For more information and a complete sample how to access properties of recipients from a Visual Basic application or Visual Basic Script, please see the following articles in the Microsoft Knowledge Base:

Extended MAPI

To retrieve the property using Extended MAPI, use the IMAPIProp::GetProps() method on the IMailUser object, or the HrGetOneProp() function. You must ensure that the recipient has been resolved to the Microsoft Exchange Server Global Address List.
