When you want to adjust the Maximum Attachement Size in Exchange 2007, you can use this script to check where the size limits are set.

The only Message Size limit that is not set through Powershell, is the one for Outlook Web Access. This is done through the web.config file on the Client Access Server.

• First make a backup of the web.config file (default location c:\Program Files\Microsoft\ExchangeServer\ClientAccess\Owa).
• Open the file with Notepad
• Change the line <httpRuntime maxRequestLength=”30000″ />
  Where 30000 is the maximum message size (in kilobytes)
• Save the file (nothing else needs to be done)

If it isn’t installed, install it: start /w ocsetup SNMP-SC

Remote administration

After you have enabled the remote administration, you can start the computer management add-in on your management workstation. If this is a Windows Vista machine, you probably will not be able to configure the tab (Security).

Use a Windows 2003 machine, start the computer management add-in and connect to the Windows 2008 Core Server. After that you will be able to configure the server.

For those who like to search a bit deeper, you can also configure the settings through the registry :

HKLM\System\CurrentControleSet\Services\SNMP\Parameters\

To remotely manage your Windows 2008 Servers, you can now install the Windows 2008 Remote Administration Tools.
