An Exchange Server 2010 mailbox user receives a NDR message when the user sends an email message to multiple internal users

Consider the following scenario:
  • You create a disclaimer on a computer that is running the Microsoft Exchange Server 2010 Hub Transport Server role.
  • An Exchange Server 2010 mailbox user sends an email message to multiple internal users.
  • The internal users are located in different mailbox database stores.
  • The email message contains a large attachment which is bigger than 200KB.
In this scenario, the user who sends the email message receives the following NDR message:

From: Microsoft Outlook
Sent: <Date, Time>
To: <Recipient>
Subject: Undeliverable: <subject>
Delivery has failed to these recipients or groups:
<Recipient names, addresses>
The email system had a problem processing this message. Exchange will not try to redeliver this message for you.
Diagnostic information for administrators:
Generating server: <Hub Transport Server name>
<Recipient address>
#554 5.6.0 STOREDRV.Deliver; Corrupt message content ##
This problem occurs because multiple threads are leveraged to process the affected message when the disclaimer is configured on the Hub Transport Server. A race condition is encountered, and then the contents of the message are corrupted.
To resolve this problem, install the following update rollup:
982639 Description of Update Rollup 4 for Exchange Server 2010
Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section.
