Did you try creating the property, then setting its value:

prop = objJournalEntry.UserProperties.Add("id", OlUserPropertyType.olNumber)
prop.Value = 1

Does the folder have an existing proeprty named id of another type?

Hi,

I have made a Outlook Addins which use the Journal Folder.
In the items of that folder, i add a custom properties named "id" where i
store information.
It works on every Outlook 2001 to 2003, but i have find an Outlook 2003
where this field is not added and the operation failed.
Is this a security problem ?
Tks for help !

example, adding a Journal's item :

objJournalEntry.Type = "Phone Call"
objJournalEntry.Subject = "mysubjet"

objJournalEntry.Body = " the body"

objJournalEntry.Duration = "12"

objJournalEntry.Start = "12/12/2005..."

objJournalEntry.UserProperties.Add("id", OlUserPropertyType.olNumber).Value
= 1
