如何将所选电子邮件从 RichText 格式转换为 HTML 格式？

Question

背景：我的工作地点使用 RichText 的默认电子邮件格式。许多人在他们的电子邮件中添加图像。带图片的 RichText 电子邮件比带图片的 HTML 电子邮件大得多。

我可以手动打开、编辑、将格式更改为 HTML，并保存以大大减小电子邮件的大小。格式在转换过程中保持不变。

但是，当我使用VBA打开邮件项目，更改格式并保存时，邮件没有转换。

如何使用 vba 将一组 Richtext 电子邮件更改为格式正确的 html 电子邮件，获得与使用功能区手动编辑和保存相同的结果？

下面是我的示例代码，当我运行这行代码时，我可以看到：

myMailItem.BodyFormat = olFormatHTML

转换方式与功能区的转换方式不同。

Public Sub myConvertHTML()

    Dim mySelectedItems As Selection
    Dim myMailItem As MailItem
    Dim myRichText As String
    Dim myHtmlText As String


    ' Set reference to the Selection.
    Set mySelectedItems = ActiveExplorer.Selection

    ' Loop through each item in the selection.
    For Each myMailItem In mySelectedItems

        'if the current format is RichText proceed
        If myMailItem.BodyFormat = olFormatRichText Then

            myMailItem.Display

            'this line does not convert the RichText to Html properly
            'it seems to convert the images into an attached file ATT#### that is an ole object
            'instead of converting the image and using it in html format
            'when using the Ribbon and changing the format to HTML,
            'the email is converted and formatting maintained
            myMailItem.BodyFormat = olFormatHTML

            myMailItem.Save
            myMailItem.Close olSave


        Else
            MsgBox "Already in RichText Format: " & myMailItem.Subject, vbInformation

        End If

    Next

    MsgBox "All Done. Email converted to HTML.", vbOKOnly, "Message"

    Set mySelectedItems = Nothing
    Set myMailItem = Nothing

End Sub

我尝试从内部操作功能区 VBA，但我一直无法弄清楚如何调用功能区元素

(Format Text/Format/HTML).

如有任何建议，我们将不胜感激。

感谢 Niton，这是我的最终解决方案。

Public Sub myConvertHTML002()
'takes selected list of items in Outlook and converts all mailItems that are RichText into HTML Format

    Dim mySelectedObjects As Selection
    Dim myObject As Object
    Dim myMailItem As MailItem

    Dim objItem As Object

    ' Set reference to the Selection.
    Set mySelectedObjects = ActiveExplorer.Selection

    ' Loop through each item in the selection.
    For Each myObject In mySelectedObjects

        If myObject.Class = olMail Then

            Set myMailItem = myObject

            'if the current format is RichText proceed
            If myMailItem.BodyFormat = olFormatRichText Then

                'have to display the email so we can use the command bars
                myMailItem.Display

                'special code because we can't change the format of the item from within the item
                'we have to use the ActiveInspector
                On Error Resume Next
                Set objItem = ActiveInspector.CurrentItem
                On Error GoTo 0

                If Not objItem Is Nothing Then
                    If objItem.Class = olMail Then
                        ActiveInspector.CommandBars.ExecuteMso ("EditMessage")
                        ActiveInspector.CommandBars.ExecuteMso ("MessageFormatHtml")
                    End If
                End If

                myMailItem.Close olSave

            Else

                'MsgBox "Already in RichText Format: " & myMailItem.Subject, vbInformation

            End If

        End If

    Next

    MsgBox "All Done. Email converted to HTML.", vbOKOnly, "Message"

    Set mySelectedItems = Nothing
    Set myMailItem = Nothing

End Sub

您可以使用 ExecuteMso 单击按钮。

CommandBars.ExecuteMso Method "Works on controls that are built-in buttons..."

Sub ChangeToHTML()
Dim objItem As Object
Dim objMail As mailitem

On Error Resume Next
Set objItem = ActiveInspector.currentItem
On Error GoTo 0

If Not objItem Is Nothing Then
    If objItem.Class = olMail Then
        ActiveInspector.CommandBars.ExecuteMso ("MessageFormatHtml")
    End If
End If

End Sub

为快速访问工具栏或功能区添加内置按钮时，将鼠标悬停在所选内容上时，您可以看到 MessageFormatHtml、IdMso 作为文本的最后一位。
