我正在通过Access与VBA合作创建邮件。
当我将图像大小调整为小于实际大小时，它会嵌入。当我省略尺寸或以实际尺寸放入时，图像作为附件出现。
下面是代码片段，miniplane.jpg是附件。它的实际尺寸是600x160。如果我将代码更改为300x80，则会显示。
Sub send_SHCmail()
'>>>> Declarations >>>>

Set appOutLook = CreateObject("Outlook.Application")
Set MailOutLook = appOutLook.CreateItem(olMailItem)
Dim olApp As Object

.HTMLBody = "<!DOCTYPE html>"
'Body Header
.HTMLBody = .HTMLBody & "<html><head><body>"
.HTMLBody = .HTMLBody & "<img src=""cid:Logo-Facet-01.png"" alt=""Image Missing"" width=""215.6"" height=""96.53"" style=""display: block;"" />"

首先，不要使用HTMLBody作为中间变量 - 读取和设置它是昂贵的。使用局部变量构建HTML，然后只设置一次HTMLBody属性。
如果您通过img属性设置src标记，则必须设置PR_ATTACH_CONTENT_ID属性 - 请参阅How to add images from resources folder as attachment and embed into outlook mail body in C#
