Outlook Reply or ReplyAll to an Email

Set objOutlook = CreateObject("Outlook.Application")
Set objMail = objOutlook.CreateItem(0)
objMail.To = "example@email.com"
objMail.cc = "example2@email.com"
objMail.Subject = "Mail test"
objMail.HTMLBody = "This is my message"
unload me
objMail.Display
Set objMail = Nothing
Set objOutlook = Nothing

I am trying to add in another function that help to reply a selected email but can't figure out how I can mix this with Item As Outlook.MailItem I understand that replying an email will require that.

So I would like to know how I can add on so that I can select an email, execute the macro and it will input the recipient email into objMail.To and recipient's body into objMail.HTMLBody

To simply Reply or ReplyAll selected messages try the following.

Option Explicit
Sub ReplyMSG()
    Dim olItem As Outlook.MailItem
    Dim olReply As MailItem ' Reply
    Dim olRecip As Recipient ' Add Recipient

    For Each olItem In Application.ActiveExplorer.Selection
    Set olReply = olItem.ReplyAll
    Set olRecip = olReply.Recipients.Add("Email Address Here") ' Recipient Address
        olRecip.Type = olCC
            olReply.HTMLBody = "Hello, Thank you. " & vbCrLf & olReply.HTMLBody
        olReply.Display

        'olReply.Send
    Next olItem
End Sub

To hide the recipient use use BCC Example

olRecip.Type = olBcc

To add multiple recipient just add

Set olRecip = olReply.Recipients.Add("Email Here")
Set olRecip = olReply.Recipients.Add("Email Here")
Set olRecip = olReply.Recipients.Add("Email Here")

With out Recipient try the following.

Option Explicit
Sub ReplyMSG()
    Dim olItem As Outlook.MailItem
    Dim olReply As MailItem ' Reply

    For Each olItem In Application.ActiveExplorer.Selection
    Set olReply = olItem.ReplyAll
            olReply.HTMLBody = "Hello, Thank you. " & vbCrLf & olReply.HTMLBody
        olReply.Display

        'olReply.Send
    Next olItem
End Sub
