How to display Microsoft Outlook mail content using the _IECreateEmbeded function?

I am currently working on designing a fully functional automation software for my job using AutoIt. Everything is going great but I've run into a little issue using the _IECreateEmbedded function.

My Issue:

What this part of my program is supposed to do is embed Microsoft Outlook's webpage inside of a GUI. This part works just fine. The webpage is loaded just fine and everything is displayed as it should be. I am able to view the message titles and subjects on the left side of my screen like normal, HOWEVER, when I click on the message to open it to read, nothing happens. I am also unable to compose a new message or search my inbox. I assumed this had something to do with Outlook using a script that AutoIt doesn't commonly support, but I'm not entirely sure. I tried loaded GMail into the GUI and it works perfectly. Any ideas?

Here's my current code: (The important parts at least)

; Includes
#include <GUIConstantsEx.au3>
#include <IE.au3>
#include <WindowsConstants.au3>

; Create GUI Window
$windowMain = GUICreate("Embedded Outlook Client", 1001, 701, 242, 88, BitOR($WS_MAXIMIZEBOX,$WS_MINIMIZEBOX,$WS_SYSMENU,$WS_CAPTION,$WS_POPUP,$WS_POPUPWINDOW,$WS_GROUP,$WS_TABSTOP,$WS_BORDER,$WS_CLIPSIBLINGS))
; Display GUI
GUISetState(@SW_SHOW)

; Create an outline for the Embedded Browser
$guiEmailGroup = GUICtrlCreateGroup("", 8, 48, 801, 601)
; Initiate function
Local $oIE = _IECreateEmbedded()
; Created an embedded browser
$browserObj = GUICtrlCreateObj($oIE, 20, 60, 780, 580)
; Allow the browser to be resized if the window is maximized.
GUICtrlSetResizing ( $browserObj, $GUI_DOCKAUTO)
; Navigate to Outlook
_IENavigate($oIE, "https://outlook.office.com/owa/#path=/mail")

While 1
    $nMsg = GUIGetMsg()
    Switch $nMsg
        Case $GUI_EVENT_CLOSE
            Exit
    EndSwitch
WEnd

Note: You will most likely need an Outlook account to be able to help with this solution. Any help would be GREATLY appreciated. Thank you in advance!

This is a simple example of sending an email with cdo.message

Func _INetSmtpMailCom($s_SmtpServer, $s_FromName, $s_FromAddress, $s_ToAddress, $s_Subject = "", $as_Body = "", $s_AttachFiles = "", $s_CcAddress = "", $s_BccAddress = "", $s_Importance = "Normal", $s_Username = "", $s_Password = "", $IPPort = 25, $ssl = 0)
    Local $objEmail = ObjCreate("CDO.Message")
    $objEmail.From = '"' & $s_FromName & '" <' & $s_FromAddress & '>'
    $objEmail.To = $s_ToAddress ; was $objEmail.To
    Local $i_Error = 0
    Local $i_Error_desciption = ""
    If $s_CcAddress <> "" Then $objEmail.Cc = $s_CcAddress
    If $s_BccAddress <> "" Then $objEmail.Bcc = $s_BccAddress
    $objEmail.Subject = $s_Subject
    If StringInStr($as_Body, "<") And StringInStr($as_Body, ">") Then
        $objEmail.HTMLBody = $as_Body
    Else
        $objEmail.Textbody = $as_Body & @CRLF
    EndIf
    If $s_AttachFiles <> "" Then
        Local $S_Files2Attach = StringSplit($s_AttachFiles, ";")
        For $x = 1 To $S_Files2Attach[0]
            $S_Files2Attach[$x] = _PathFull($S_Files2Attach[$x])
;~          ConsoleWrite('@@ Debug : $S_Files2Attach[$x] = ' & $S_Files2Attach[$x] & @LF & '>Error code: ' & @error & @LF) ;### Debug Console
            If FileExists($S_Files2Attach[$x]) Then
                ConsoleWrite('+> File attachment added: ' & $S_Files2Attach[$x] & @LF)
                $objEmail.AddAttachment($S_Files2Attach[$x])
            Else
                ConsoleWrite('!> File not found to attach: ' & $S_Files2Attach[$x] & @LF)
                SetError(1)
                Return 0
            EndIf
        Next
    EndIf
    $objEmail.Configuration.Fields.Item("http://schemas.microsoft.com/cdo/configuration/sendusing") = 2
    $objEmail.Configuration.Fields.Item("http://schemas.microsoft.com/cdo/configuration/smtpserver") = $s_SmtpServer
    If Number($IPPort) = 0 Then $IPPort = 25

    ;Authenticated SMTP
    If $s_Username <> "" Then
        $objEmail.Configuration.Fields.Item("http://schemas.microsoft.com/cdo/configuration/smtpauthenticate") = 1
        $objEmail.Configuration.Fields.Item("http://schemas.microsoft.com/cdo/configuration/sendusername") = $s_Username
        $objEmail.Configuration.Fields.Item("http://schemas.microsoft.com/cdo/configuration/sendpassword") = $s_Password
    EndIf
    If $ssl Then
        $objEmail.Configuration.Fields.Item("http://schemas.microsoft.com/cdo/configuration/smtpusessl") = True
    EndIf
    ;Update settings
    $objEmail.Configuration.Fields.Update
    ; Set Email Importance
    Switch $s_Importance
        Case "High"
            $objEmail.Fields.Item("urn:schemas:mailheader:Importance") = "High"
        Case "Normal"
            $objEmail.Fields.Item("urn:schemas:mailheader:Importance") = "Normal"
        Case "Low"
            $objEmail.Fields.Item("urn:schemas:mailheader:Importance") = "Low"
    EndSwitch
    $objEmail.Fields.Update
    ; Sent the Message
    $objEmail.Send
    If @error Then
        SetError(2)
        Return $oMyRet[1]
    EndIf
    $objEmail = ""
EndFunc   ;==>_INetSmtpMailCom
; Com Error Handler
Func MyErrFunc()
    $HexNumber = Hex($oMyError.number, 8)
    $oMyRet[0] = $HexNumber
    $oMyRet[1] = StringStripWS($oMyError.description, 3)
    ConsoleWrite("### COM Error !  Number: " & $HexNumber & "   ScriptLine: " & $oMyError.scriptline & "   Description: " & $oMyRet[1] & @LF)
    SetError(1); something to check for when this function returns
    Return
EndFunc   ;==>MyErrFunc

Now if you want to build an email client I don't know how much it could help. An other alternative could be WinHTTP.
