INTRODUCTION
When you send Simple Mail Transfer Protocol (SMTP) mail to a Microsoft Exchange 2000 Server or a Microsoft Exchange Server 2003 public folder, the message class is IPM.Post. In Microsoft Exchange Server 5.5, the message class of a message that is sent to a public folder is IPM.Note. Therefore, if you have a message-archiving system where the e-mail messages must be stored without being changed or converted, you may not be able to archive messages from the public folder. This article describes an update that you can use to configure the setting of the PR_MESSAGE_CLASS attribute of SMTP messages that are sent to public folders as IPM.Note instead of as IPM.Post.

Note &quot;SMTP mail&quot; refers to mail that is not from a MAPI source.

Hotfix installation information
After you install this update, the message class of incoming messages to public folders may be changed to IPM.Note (instead of IPM.Post). You can configure this new setting by creating the &quot;Incoming defaults to IPM.Note&quot; registry value in the following registry subkey:

Value name: Incoming defaults to IPM.Note

Value type: DWORD

Value data: 0 or 1 (0 is default value) (0=false)

Important This value name is case-sensitive. The default behavior without the registry key is that incoming messages appear as IPM.Post. If you set the registry value to 0 (zero), the default behavior continues, and incoming messages appear as IPM.Post. If you set the registry value to 1, the behavior changes, and new SMTP mail messages from a non-MAPI source appear as IPM.Note.

To enable this functionality, you must configure these registry settings on all Exchange servers that host public folders. You do not have to configure these registry settings on Exchange servers that do not host public folders. Additionally, you must configure these registry settings for each public folder database on the particular server where you want to enable this functionality.

After you make these registry changes, you must restart the Microsoft Exchange Information Store service to enable this new functionality.



STATUS
Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the &quot;Applies to&quot; section.
