BeforeAttachmentSave Event
Occurs just before an attachment is saved.
Sub object_BeforeAttachmentSave(ByVal Attachment As Attachment, Cancel As Boolean)
object An expression that evaluates to one of the objects in the Applies To list. In VBScript, use the word Item.
Attachment Required. The Attachment to be saved.
Cancel Optional (not used in VBScript). False when the event occurs. If the event procedure sets this argument to True, the save operation is not completed and the attachment is not changed.
Remarks
In VBScript, if you set the return value of this function to False, the save operation is cancelled and the attachment is not changed.
Example
This VBScript example notifies the user that the user is not allowed to save the attachment. It returns False to cancel the save operation.
Function Item_BeforeAttachmentSave(ByVal SaveAttachment)
MsgBox "You are not allowed to save " & SaveAttachment.Name
Item_BeforeAttachmentSave = False
End Function
