Hi There,

Refer to the link below (Properties section),

https://docs.microsoft.com/en-us/office/vba/api/outlook.documentitem

Other than all the mentioned properties (in Outlook, they are columns) in the above link, are there any properties we can use ?

Or actually we can create our own column for DocumentItem programatically ?

Best Regards,
Jun Wei

Hello Jun,

You can create a UserProperty: 1) get the UserProperties collection object via {an Outlook item such as DocumentItem}.UserProperties, 2) add a UserProperty to the collection via newUserProperty = theUserProperties.Add(), 3) set value on the user property added: newUserProperty.Value={...}, 4) release newUserProperty and theUserProperties, 5) save the item.

For the user property to be shown in the view, you need to modify the current view or create a new one. When doing this, modify the MAPIFolder.UserDefinedProperties collection of the folder in question so that the user property is listed. Note that UserProperties.Add() provides a parameter that adds the user property to the folder (in addition to adding it to the current item)

In the Outlook Explorer UI, you modify the view in the following way:
- Click View Settings on the View tab.
- Click Columns....
- In the Select available columns from drop down, select User-defined field in folder.
- Select a user property in the Available columns list and click Add.
- Optionally, reposition the user property column in the Show these columns in this order list: use the Move Up and Move Down buttons.

Hi Andrei,

I do according what you said, here is my source code:

1- Dim fld As Outlook.UserProperties
2- fld = OutlookApp.ActiveExplorer.Selection.Item(1).UserProperties (this is DocumentItem, not MailItem, tested with MailItem, no exception occurred.)
3- Dim fld2 As Outlook.UserProperty
4- fld2 = fld.Add("Column2", Outlook.OlUserPropertyType.olText)
5- fld2.Value = "abc"
6- OutlookApp.ActiveExplorer.Selection.Item(1).Save()

When it comes to the line 5, exception occurred.

What could possibly caused the exception happened ?

Best Regards,
Jun Wei

What exception exactly?

I believe in your actual code you release the COM objects this code line creates.

Hi Andrei,

It says "The object doesn't support this method".

But I did not release any COM objects yet.

Can it be that the user property is already added to that item and your code doesn't foresee this yet?

I suppose you get an exception on the previous line: 4- fld2 = fld.Add("Column2", Outlook.OlUserPropertyType.olText)

Hi Andrei,

No, there is no exception happens in line 4, it only happens in line 5.

Could it anything wrong with my source code ?

I tried with MailItem, it has no exception at all.

But what I'm trying is DocumentItem, could you advise ?

Best Regards,

Hello Jun Wei,

Does the issue occur after you turn off all other COM add-ins and restart Outlook?

Set a breakpoint on that line. In the Locals window, what is the exact type of the fld2 variable?
