You have not mentioned the Exchange server version. However, you can refer to the below MS KB article to see if your problem is related.

Found this article which shows the same issue as yours;


I just had this issue and was able to resolve with the MS Outlook Engineering team as well as the Exchang Connectors Team.

Active Directory : 08R2 Std
Exchange: Exchange 2010 SP1RU4 Standard on 08R2 Standard
1 DC, 1 EXC, 80 Users
Users report that some attachments from some external senders are not displayed on Microsoft Outlook 2010
Users report that when they go into OWA the attachment not displayed in Outlook shows in the preview pane and in the message window. However no paperclip is displayed in the navigation pane
Users report attachments not displayed in Outlook are displayed in BLackberry devices.
Users report that when forwarding messages to external users, external users are able to see attachments.
Users report that when forwarding messages to other internal users, attachments are still not displayed.
Users report than when the attachment is stripped off and re-attached, they are able to view attachments correctly.
Microsoft resolution steps. (Non-4-Hour version)
Viewed header information
Put pipeline tracing on affected sender
Resolution Attempt #1
Stop Exchange Transport service
Navigate to C:\program files\exchange\v14\bin
Edit the EdgeTransport.exe.Config file
Add <add key="TreatInlineDispositionAsAttachment" value="true" /> between the <appsettings> and </appsettings>
restart transport service
HAve affected external user re-send email
Attachment showed in Outlook as it does in OWA, however the paperclip icon was not displayed....
OK... Half way there...
Resolution 2
Compared Content-Type headers of message that Microsoft forwarded back to me, vs the message they stripped and reattached and then re-sent.
Good Message

Content-Type: multipart/mixed;
Bad Message

Content-Type: multipart/related;

The "multipart/mixed" and "multipart/alternate" showing in the content-type were the issue.
Setup a transport rule to change these back to multipart/mixed as per the below

1. Launch Exchange Management Console
2. Expand Organization Configuration, and select Hub Transport
3. On the right-hand Action Pane, select New Transport Rule …

4. Give the rule a name (Ex:- Paperclip icon not showing)
5. Select when the message header contains text patterns, click the highlighted “message header”, Type "Content-Type" click OK, and then click the highlighted “text patterns”, Type "multipart/related" click Add, click OK, and then click Next
6. Select “set header with value,” click the highlighted “header” text, type “Content-Type”, click OK
8. Click the highlighted “value” text, type multipart/mixed, click OK, and then click
9. Next
10. On the “Exceptions” page, simply click next
11. At the final “Create Rule” page, click New, and then click Finish

Restart the transport service
Had user re-send message. Message delivered successfully.
Hope this helps and perhaps saves a 4+ hour call to Microsoft...
