可以使用以下代码检查是否已经登录Outlook账户,并自动登录并发送邮件:
```
Sub SendEmail()
Dim olApp As New Outlook.Application
Dim olNs As Outlook.Namespace
Dim olRecip As Outlook.Recipient
Dim olMsg As Outlook.MailItem
Dim sBody As String
Dim sSubject As String
Dim sTo As String
' Check if Outlook is logged in
Set olNs = olApp.GetNamespace("MAPI")
If Not olNs.CurrentUser Is Nothing Then
' Outlook is already logged in, proceed with sending email
sTo = "example@example.com"
sSubject = "Test Email"
sBody = "This is a test email."
Set olMsg = olApp.CreateItem(olMailItem)
Set olRecip = olMsg.Recipients.Add(sTo)
olRecip.Type = olTo
olMsg.Subject = sSubject
olMsg.Body = sBody
olMsg.Send
Set olRecip = Nothing
Set olMsg = Nothing
Else
' Outlook is not logged in, prompt user to log in
olNs.Logon
' Send email after logging in
SendEmail
End If
Set olNs = Nothing
Set olApp = Nothing
End Sub
```
在代码中,先使用 `olApp.GetNamespace("MAPI")` 获取Outlook命名空间,然后使用 `olNs.CurrentUser` 检查是否已经登录Outlook账户。如果 `olNs.CurrentUser` 不是 `Nothing` ,则表示Outlook已经登录,可以直接发送邮件;否则,使用 `olNs.Logon` 登录Outlook,然后再调用 `SendEmail` 子过程发送邮件。
请注意,使用 `olNs.Logon` 方法会弹出Outlook登录对话框,需要手动输入用户名和密码进行登录,无法自动登录。此外,Outlook要求用户手动确认发送邮件,无法完全自动发送邮件。
