The information in this article applies to:
When attempting to set the value of a field (property) of a Collaboration Data Objects (CDO) object, the following error may occur:
MAPI_E_NOT_FOUND.
The field probably does not yet exist in the underlying Messaging Application Programming Interface (MAPI) object.
Instead of just setting the field value, proceed from the assumption that the field does not exist. Use the Add method of the Fields collection, which facilitates both adding the field and setting the value as follows:
objMsg.Fields.Add &H00150040, 234
The sample above demonstrates adding and setting the value for the
PR_EXPIRY_LIMIT (&H00150040) field. No error occurs if the property already
exists.
This behavior is by design.
1. Create a message object called objMsg.
2. Try to set a property not directly exposed by CDO (such as
PR_EXPIRY_LIMIT (&H00150040)):
objMsg.Fields(&H00150040) = 234
3. Note that the above statement fails with this error:
MAPI_E_NOT_FOUND.
