Excel VBA 可以使用 Outlook 客户端来发送电子邮件。下面提供一个简单的示例代码：
Sub SendEmail()
Dim OutApp As Object
Dim OutMail As Object
Dim strto As String, strcc As String, strbcc As String, strsub As String, strbody As String
Set OutApp = CreateObject("Outlook.Application")
Set OutMail = OutApp.CreateItem(0)
strto = "recipient1@example.com; recipient2@example.com"
strcc = "ccaddress@example.com"
strbcc = "bccaddress@example.com"
strsub = "邮件主题"
strbody = "邮件正文"
On Error Resume Next
With OutMail
.To = strto
.CC = strcc
.BCC = strbcc
.Subject = strsub
.HTMLBody = strbody
.Display '或 .Send 发送
End With
On Error GoTo 0
Set OutMail = Nothing
Set OutApp = Nothing
End Sub
在上述代码中，您可以将电子邮件的收件人、抄送、密送、主题和正文等信息替换为您实际需要的信息。另外，通过 .Display 方法，您可以启动 Outlook 客户端并显示电子邮件，这样您可以检查邮件内容并手动发送。如果您想自动发送，只需用 .Send 方法替换 .Display 即可。
