UserDefinedProperty Object (Outlook)

Represents the definition of a user-defined property for a Folder object.

Version Added: Outlook 2007

Use UserDefinedProperties(index), where index is a name or index number, to return a single UserDefinedProperty object.

Use the Add method of the UserDefinedProperties collection for a Folder object to define a user-defined property for that folder.

Use the Type property to return the user-defined property type and the DisplayFormat property to return the display format for the user-defined property. If the Type property is set to olCombination or olFormula, use the Formula property to return the formula used to generate values for the user-defined property.

The UserDefinedProperty object represents only the definition of a user-defined property, which is applicable to all Outlook items contained by the folder. To retrieve or change user-defined property values for an Outlook item in that folder, use the UserProperties property of the Outlook item, such as a MailItem object, to retrieve the UserProperties collection for that item. You can then use the UserProperty object for the appropriate user-defined property to retrieve or change the value of that user-defined property for the Outlook item.

The following Visual Basic for Applications (VBA) example displays the name of a specified Folder object, as well as the name and type of every UserDefinedProperty object contained in the UserDefinedProperties collection of the specified Folder object, to the Immediate window.

Sub DisplayUserProperties(ByRef FolderToCheck As Folder) 
 Dim objProperty As UserDefinedProperty 
 
 ' Print the name of the specified Folder object 
 ' reference to the Immediate window. 
 Debug.Print "--- Folder: " & FolderToCheck.Name 
 
 ' Check if there are any user-defined properties 
 ' associated with the Folder object reference. 
 If FolderToCheck.UserDefinedProperties.Count = 0 Then 
 ' No user-defined properties are present. 
 Debug.Print " No user-defined properties." 
 Else 
 ' Iterate through every user-defined property in 
 ' the folder. 
 For Each objProperty In FolderToCheck.UserDefinedProperties 
 ' Retrieve the name of the user-defined property. 
 strPropertyInfo = objProperty.Name 
 ' Retrieve the type of the user-defined property. 
 Select Case objProperty.Type 
 Case OlUserPropertyType.olCombination 
 strPropertyInfo = strPropertyInfo & " (Combination)" 
 Case OlUserPropertyType.olCurrency 
 strPropertyInfo = strPropertyInfo & " (Currency)" 
 Case OlUserPropertyType.olDateTime 
 strPropertyInfo = strPropertyInfo & " (Date/Time)" 
 Case OlUserPropertyType.olDuration 
 strPropertyInfo = strPropertyInfo & " (Duration)" 
 Case OlUserPropertyType.olEnumeration 
 strPropertyInfo = strPropertyInfo & " (Enumeration)" 
 Case OlUserPropertyType.olFormula 
 strPropertyInfo = strPropertyInfo & " (Formula)" 
 Case OlUserPropertyType.olInteger 
 strPropertyInfo = strPropertyInfo & " (Integer)" 
 Case OlUserPropertyType.olKeywords 
 strPropertyInfo = strPropertyInfo & " (Keywords)" 
 Case OlUserPropertyType.olNumber 
 strPropertyInfo = strPropertyInfo & " (Number)" 
 Case OlUserPropertyType.olOutlookInternal 
 strPropertyInfo = strPropertyInfo & " (Outlook Internal)" 
 Case OlUserPropertyType.olPercent 
 strPropertyInfo = strPropertyInfo & " (Percent)" 
 Case OlUserPropertyType.olSmartFrom 
 strPropertyInfo = strPropertyInfo & " (Smart From)" 
 Case OlUserPropertyType.olText 
 strPropertyInfo = strPropertyInfo & " (Text)" 
 Case OlUserPropertyType.olYesNo 
 strPropertyInfo = strPropertyInfo & " (Yes/No)" 
 Case Else 
 strPropertyInfo = strPropertyInfo & " (Unknown)" 
 End Select 
 
 ' Print the name and type of the user-defined property 
 ' to the Immediate window. 
 Debug.Print strPropertyInfo 
 Next 
 End If 
End Sub
