SYMPTOMS

When you try to open a 2007 Microsoft Office system file attachment by using Microsoft Office Outlook Web Access, you may receive the following error message:

To open this attachment, you must save it to your disk, right-click the link, and then click Save.

This problem occurs if the following conditions are true:

RESOLUTION

To resolve this problem, add the 2007 Office system content types to Exchange so that the conversion process can recognize these content types. A content type is a string that has a file name extension associated with it. To add the string and the associated file name extension, use Exchange System Manager. To do this, follow these steps:

The Microsoft Exchange Information Store service stops responding (hangs) 24 to 36 hours after you enable an antivirus program that uses the Microsoft Virus Scanning Application Programming Interface (VSAPI) in Microsoft Exchange Server 2003. Sybari Antigen for Microsoft Exchange is an example of such a program.

Additionally, the Microsoft Exchange Information Store service may stop responding (hang) when you perform a backup of Exchange Server 2003.

Additionally, an event that resembles the following event may be logged in the Application log:

Event Type: Error
Event Source: Application Error
Event Category: (100)
Event ID: 1000
Description: Faulting application store.exe, version 6.5.xxxx.xx, faulting module exsmtp.dll, version 6.5.7638.1, fault address 0×000096f6.

Hotfix 

RESOLUTION

1. Start the Exchange System Manager.
2. Click to expand the Recipients container.
3. Right-click All Address Lists, point to New, and then click Address List.
4. Click the Filter Rules button and verify that it is set to Exchange Recipients (the default setting).
5. Click the Advanced tab, click Field, and then click User.
6. Click E-mail Address.
7. In the Condition box, click Starts with, and then in the empty box to the right, type the first few letters of the address that you want to search for.
8. Check the lower window for matches.

If you find objects that have the same e-mail address as the one you are trying to add, either change the e-mail address for this object or delete the address if it is longer needed.

Repeat the same process for public folders, contacts and groups, but use the following modifications:

1. In step 5, point to User, and then change the setting to Public Folder, to Contact, or to Group.
2. In step 6, click E-mail Address or Alias if the E-mail Address option is not available.

Create the event sink

To create an event sink, paste the following code in a new file and save it as EventSinkScript.vbs.

<script language=”VBScript”>
Sub ISMTPOnArrival_OnArrival(ByVal Msg, EventStatus)
   TextDisclaimer = vbCrLf & “DISCLAIMER:” & vbCrLf & “Sample Disclaimer added in a VBScript.”
   HTMLDisclaimer = “

DISCLAIMER:
Sample Disclaimer added in a VBScript.”

If Msg.HTMLBody <> “” Then
      ‘Search for the “” tag and insert our disclaimer before that tag.
      pos = InStr(1, Msg.HTMLBody, “”, vbTextCompare)
      szPartI = Left(Msg.HTMLBody, pos – 1)
      szPartII = Right(Msg.HTMLBody, Len(Msg.HTMLBody) – (pos – 1))
      Msg.HTMLBody = szPartI + HTMLDisclaimer + szPartII
   End If

If Msg.TextBody <> “” Then
      Msg.TextBody = Msg.TextBody & vbCrLf & TextDisclaimer & vbCrLf
   End If

‘Commit the content changes to the transport ADO Stream object.
   Msg.DataSource.Save ‘ Commit the changes into the transport Stream

EventStatus = cdoRunNextSink
End Sub
</script>

Register the event sink

To register your event sink, use the Smtpreg.vbs file, which is installed with the Exchange SDK. From a command prompt, browse to the …\Exchange SDK\SDK\Support\CDO\Scripts folder and type the following (make sure that the path to EventSinkScript.vbs is correct):
cscript smtpreg.vbs /add 1 onarrival SMTPScriptingHost CDO.SS_SMTPOnArrivalSink “mail from=*@your-domain-here.com”

cscript smtpreg.vbs /setprop 1 onarrival SMTPScriptingHost Sink ScriptName “C:\EventSinkScript.vbs”

If the command succeeds, you receive a success message generated by the script.

To unregister this event, type the following:

cscript smtpreg.vbs /remove 1 OnArrival SMTPScriptingHost

For more information on registering events with Smtpreg.vbs, see the “Managing Event Bindings” topic on the following MSDN Web site:
