mapi控件发送email时出现“unspecified failure has occurred”异常提示

mapi控件发送email时出现“unspecified failure has occurred”错误提示
在vb中用mapi控件发送email时出现“unspecified failure has occurred”错误提示，奇怪的是有些电脑上会出错，有些又不会？！ 公司所有电脑上都安装了office 2003,会不会是outlook express与office 2003 outlook有冲突，如果是为什么有些电脑上又没问题呢？



以下是我的代码，哪位高手帮忙看看。

--------------------------------------------
  If bLoggedon = False Then
  With mapSess
  .DownLoadMail = False
  .LogonUI = True
  .SignOn
  .NewSession = True
  mapMess.SessionID = .SessionID
  End With
  bLoggedon = True
  End If
  Screen.MousePointer = vbDefault
 
  With mapMess
  .Compose
  .MsgSubject = "Order Confirmation"
  .MsgNoteText = "The attached is a confirmation list of your current order."
  If pRecipAddress <> "" Then
  .RecipAddress = pRecipAddress
  End If
  .MsgIndex = -1
  .AttachmentPathName = EmailFileName
  .Send True  
  End With
