Checking the Message Size Limits in Exchange Server 2007.

If you don't have SP1 installed in your Exchange Server 2007. You can check the message size limit through the Exchange Shell.

In Exchange Shell, type Get-TransportConfig [Enter] to see the current message size setting.

To update the MaxReceiveSize and MaxSendSize, use the command below. We are going to change the setting to accept send and receive size to 40MB. This is more than enough for email attachment. If you need a bigger file attachment, I highly recommend to use FTP file transfer tool instead of your email system.


In Exchange Shell, type:
Set-TransportConfig -MaxReceiveSize 40MB -MaxSendSize 40MB [Enter]

In Exchange Server 2007 with SP1, you can set it using the Exchange Management Console. In Organization Configuration, Hub Transport, Global Setting tab, Transport Setting, click on Properties, set Maximum receive size and Maximum Send Size.
