You receive a "Message too large for this recipient" NDR that has the original message attached after you restrict the Maximum Message Send Size value in Exchange Server 2007
Article ID: 960775 - View products that this article applies to.
After you restrict the Maximum Message Send Size value for a Microsoft Exchange Server 2007 organization by using the Set-TransportConfig cmdlet, Microsoft Outlook clients cannot send messages that are larger than the specified size. However, some old version Outlook clients, such as Microsoft Office Outlook 2003 Service Pack 1 (SP1) or earlier, do not recognize the restriction. Therefore, a large message will be submitted to an Exchange 2007 server if the clients are running in Cache mode.
In these cases, the Exchange server will generate the following Non Delivery Report (NDR) message that has the original e-mail attached:
#550 5.2.3 RESOLVER.RST.RecipSizeLimit; message too large for this recipient ##
Note This NDR indicates that the message size exceeds restrictions.
Under certain conditions, if a message is large or if there is a high volume of these message, you may notice the following performance issues:
To resolve this problem, install Update Rollup 8 for Exchange 2007 Service Pack 1.

To work around this problem, block older versions of Outlook, such as Microsoft Office Outlook 2003 RTM and Outlook 2003 SP1 and earlier versions. These versions do not honor the maximum send size for the organization. However, if the application that is submitting the message is not an Outlook client, there is no known workaround to prevent the message from being submitted.
