MailItem.BeforeCheckNames Event

  • Article
Outlook Developer Reference

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

Syntax

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.

Remarks

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.

Example

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.

Visual Basic for Applications 
  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
