I don't believe you can size the msgbox but you can position it:

This example positions the msgbox to the right of Excel's window:

Type RECT
Left As Long
Top As Long
Right As Long
Bottom As Long
End Type

Public Declare Function UnhookWindowsHookEx Lib "user32" ( _
ByVal hHook As Long) As Long
Public Declare Function GetWindowLong Lib "user32" Alias _
"GetWindowLongA" (ByVal hwnd As Long, ByVal nIndex As Long) _
As Long
Public Declare Function GetCurrentThreadId Lib "kernel32" () As Long
Public Declare Function SetWindowsHookEx Lib "user32" Alias _
"SetWindowsHookExA" (ByVal idHook As Long, ByVal lpfn As Long, _
ByVal hmod As Long, ByVal dwThreadId As Long) As Long
Public Declare Function SetWindowPos Lib "user32" ( _
ByVal hwnd As Long, ByVal hWndInsertAfter As Long, _
ByVal x As Long, ByVal y As Long, ByVal cx As Long, _
ByVal cy As Long, ByVal wFlags As Long) As Long
Public Declare Function GetWindowRect Lib "user32" (ByVal hwnd _
As Long, lpRect As RECT) As Long
Public Declare Function GetActiveWindow Lib "user32" () As Long
Public Declare Function FindWindow Lib "user32" Alias "FindWindowA" _
(ByVal lpClassName As String, ByVal lpWindowName As String) As Long


Public Const GWL_HINSTANCE = (-6)
Public Const SWP_NOSIZE = &H1
Public Const SWP_NOZORDER = &H4
Public Const SWP_NOACTIVATE = &H10
Public Const HCBT_ACTIVATE = 5
Public Const WH_CBT = 5
Public hHook As Long
Public hXL As Long

Sub ShowMsgBox()
Dim hInst As Long
Dim Thread As Long
hXL = FindWindow("XLMAIN", Application.Caption)
hInst = GetWindowLong(hXL, GWL_HINSTANCE)
Thread = GetCurrentThreadId()
hHook = SetWindowsHookEx(WH_CBT, AddressOf WinProc, hInst, Thread)
MsgBox "This message box has been positioned to the top right of
Excel's
window."
End Sub

Function WinProc(ByVal lMsg As Long, ByVal wParam As Long, _
ByVal lParam As Long) As Long
Dim rectXL As RECT, rectMsg As RECT
Dim x As Long, y As Long
Dim hMsgbox As Long

If lMsg = HCBT_ACTIVATE Then
hMsgbox = GetActiveWindow
GetWindowRect hXL, rectXL
GetWindowRect wParam, rectMsg
x = (rectXL.Left + (rectXL.Right - rectXL.Left) * 0.75) - _
((rectMsg.Right - rectMsg.Left) / 2)
y = (rectXL.Top + (rectXL.Bottom - rectXL.Top) * 0.3) - _
((rectMsg.Bottom - rectMsg.Top) / 2)
SetWindowPos wParam, 0, x, y, 0, 0, _
SWP_NOSIZE Or SWP_NOZORDER Or SWP_NOACTIVATE
UnhookWindowsHookEx hHook
End If
WinProc = False
End Function
