In a table view, bring up the Field Chooser and click New to add a new field. Programmatically, use the ContactItem.UserProperties.Add method on each item that needs the new field.

In my experiments it Outlook I see that Outlook allows user-defined
fields, but I haven't seen a way to create a user defined field for
the whole contact database.

Is there a way to create one?

I need to synchronize Outlook contacts with another database, so that
new contacts entered in Outlook will be added to the other database
and the other way round. If I can create globally additional fields I
will be able to use one of the columns for synchronization checks, as
the Outlook StoreId can change if databases get copied or moved
around.

PS. Will the new fields appear as properties in the dispatch interfaces
