Configure Outlook to Expose Original Sender Field in the Quarantine Mailbox

 

Applies to: Exchange Server 2010 SP3, Exchange Server 2010 SP2

Spam quarantine is a feature of the Content Filter agent that reduces the risk of losing legitimate messages. Spam quarantine provides a temporary storage location for messages that are identified as spam and that shouldn't be delivered to a user mailbox inside the organization.

When a message meets the spam quarantine threshold, it's wrapped in a non-delivery report (NDR) and delivered to the spam quarantine mailbox. Because the quarantined messages are stored as NDRs in the quarantine mailbox, the postmaster address of your organization will be listed as the From: address for all messages.

However, having the original sender address in the field list would make it easier to locate the message you want to recover. This topic explains how you can create a custom Outlook form and modify the default view to expose the original sender address in the list of messages.

Prerequisites

• A spam quarantine mailbox is configured. For more information, see Specify a Spam Quarantine Mailbox.

• You have been granted owner rights to the spam quarantine mailbox.

• You have an Outlook profile configured to access the spam quarantine mailbox on the management workstation you'll be using to perform this procedure.

Configure Outlook to expose original sender field in the quarantine mailbox

You need to be assigned owner permissions to the quarantine mailbox in Microsoft Office Outlook before you can perform this procedure.

The original sender field isn't a default field that you can choose. Therefore, before you can add the original sender field in the message view, you must first create an Outlook form that will add the original sender field as an option. After you create this custom form, you can then configure Microsoft Office Outlook 2007 to expose the original sender field in the message view.

1. Open an ASCII text editor, such as Notepad, and copy the following code into the document.

   [Description] 
   MessageClass=IPM.Note
   CLSID={00020D31-0000-0000-C000-000000000046} 
   DisplayName=Quarantine Extension Form 
   Category=Standard 
   Subcategory=Form 
   Comment=This forms allows the Original Sender Address to be viewed as a column 
   LargeIcon=IPML.ico 
   SmallIcon=IPMS.ico 
   Version=1.0 
   Locale=enu 
   Hidden=1 
   Owner=Microsoft Corporation 
   Contact=Your Name
   [Platforms] 
   Platform1=Win16 
   Platform2=NTx86 
   Platform9=Win95 
   [Platform.Win16] 
   CPU=ix86 
   OSVersion=Win3.1 
   [Platform.NTx86] 
   CPU=ix86 
   OSVersion=WinNT3.5 
   [Platform.Win95] 
   CPU=ix86 
   OSVersion=Win95 
   [Properties] 
   Property01=OriginalSenderAddress 
   [Property.OriginalSenderAddress] 
   Type=30 
   NmidInteger=0x0067 
   DisplayName=Original Sender Address 
   [Verbs] 
   Verb1=1 
   [Verb.1] 
   DisplayName=&Open 
   Code=0 
   Flags=0 
   Attribs=2 
   [Extensions] 
   Extensions1=1 
   [Extension.1] 
   Type=30 
   NmidPropset={00020D0C-0000-0000-C000-000000000046} 
   NmidInteger=1 
   Value=1000000000000000
   

2. Save the file with a .cfg file name extension to a location on the local hard disk. For the rest of this procedure, we assume that the file is named QTNE.cfg.

3. If Outlook isn't open, start Outlook with the profile configured for the quarantine mailbox.

4. In Outlook 2007 on a client computer, click Tools, and then click Options.

5. In the Options dialog box, click the Other tab, and then under General, click Advanced Options.

6. In the Advanced Options dialog box, click Custom Forms, and then in the Custom Forms dialog box, click Manage Forms.

7. In the Forms Manager dialog box, click Install. Locate the directory where you saved QTNE.cfg in step 2. Select QTNE.cfg, and then click Open to install QTNE.cfg as the Quarantine Extension Form in your Personal Forms library.

8. Close the Forms Manager dialog box, and then click OK to close the remaining dialog boxes and return to the main Outlook interface. In the default message view of Outlook, in the Inbox, right-click the column heading row, and then select Field Chooser.

   Note

   If you don't see Field Chooser as an option, you may need to expand the width of your message list.

9. In the Field Chooser drop-down menu, click Forms. You may have to scroll to find Forms.

10. In the Select Enterprise forms for this Column dialog box, from the drop-down menu, select Personal Forms, expand the Standard form, and then select Quarantine Extension Form. Click Add, and then click Close.

    Note

    In some cases, you may have to remove the default Message form to add the Quarantine Extension Form.

11. In the Field Chooser dialog box, drag the OriginalSenderAddress property into the column heading row.
