MailItem.BeforeCheckNames Event (Outlook)

Occurs just before Microsoft Outlook starts resolving names in the recipient collection for an item (which is an instance of the parent object).

expression .BeforeCheckNames(Cancel)

expression A variable that represents a MailItem object.

Parameters

Name

Required/Optional

Data Type

Description

Cancel

Required

Boolean

False when the event occurs. If the event procedure sets this argument to True, the name resolution process is not completed.

You use the BeforeCheckNames event in VBScript, but the event does not fire when an e-mail name is resolved on the form.

The event does not fire under the following circumstances:

  • You customized a Journal Entry form and then resolved a contact in the Contacts field.

  • You customized a Contact form and then resolved a contact in the Contacts field.

  • You customized any type of form and Outlook automatically resolved the name in the background.

  • You programmatically created and resolved a recipient.

This Visual Basic for Applications (VBA) example asks the user if the user wants to resolve names and returns False to cancel the operation if the user answers no. The sample code must be placed in a class module such as ThisOutlookSession, and the SendMail() procedure should be called before the event procedure can be called by Outlook.

Public WithEvents myItem As Outlook.MailItem 
 
 
 
Private Sub myItem_BeforeCheckNames(Cancel As Boolean) 
 
 If MsgBox("Do you want to resolve names now?", 4) = vbOK Then 
 
 Cancel = True 
 
 End If 
 
End Sub 
 
 
 
Public Sub SendMail() 
 
 Set myItem = Application.CreateItem(olMailItem) 
 
 myItem.Recipients.Add ("Dan Wilson") 
 
 myItem.Recipients.Add ("Nate Sun") 
 
 myItem.Body = "Good morning!" 
 
 myItem.Send 
 
End Sub
