SYMPTOMS

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:
  • Slow response for message processing and client access
  • Database and transaction logs that grow rapidly
  • Version Store issued on the Transport servers

    Note The Version Store is an allocation of memory in which database transactions are held until they can be written to the disk. For Transport servers, the message delivery is very slow and may be stopped if almost all the Version Store memory has been used.

RESOLUTION

To resolve this problem, install Update Rollup 8 for Exchange 2007 Service Pack 1.

For more information about Update Rollup 8 for Exchange Server 2007 Service Pack 1, see the following Exchange Help topic:
Description of Update Rollup 8 for Exchange Server 2007 Service Pack 1
For more information about how to obtain the latest Exchange service pack or update rollup, see the following Exchange Help topic:

WORKAROUND

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.
