You will need to modify the registry on the server, OWA config blocks certain formats as dafaults.

See - http://support.microsoft.com/kb/830827

This is the bit relevent to your problem -

Blocking attachments
With Outlook Web Access, you can block users from opening, sending, or receiving specified attachment types. In particular, you can do the following:

    * Prevent users from accessing certain file type attachments. By default, all new Exchange 2003 installations block attachments of Levels 1 and 2 file types and Levels 1 and 2 MIME types. This feature is particularly useful in stopping Outlook Web Access users from opening attachments at public Internet terminals. Opening attachments at public Internet terminals could potentially compromise corporate security. If an attachment is blocked, a warning message indicating that the user cannot open the attachment appears in the InfoBar of the e-mail message. Outlook Web Access users who are working in their offices or who are connected to the corporate network from home can open and read attachments. You can enable full intranet access to attachments by providing the URL to the back-end servers and permitting attachments on the Exchange back-end servers.
    * Prevent users from sending or receiving attachments with specific file name extensions that could contain viruses. This feature in Outlook Web Access matches the attachment blocking functionality in Outlook. For received messages, a warning message indicating that an attachment is blocked appears in the InfoBar of the e-mail message. For sent messages, users cannot upload any files with extensions that appear on the block list.

To change the attachment blocking settings, you must modify the registry settings on the server.

Note In a front-end / back-end configuration, the registry modifications should be made on the back-end server.

To do this, follow these steps.

Important This section, method, or task contains steps that tell you how to modify the registry. However, serious problems might occur if you modify the registry incorrectly. Therefore, make sure that you follow these steps carefully. For added protection, back up the registry before you modify it. Then, you can restore the registry if a problem occurs. For more information about how to back up and restore the registry, click the following article number to view the article in the Microsoft Knowledge Base:
322756  (http://support.microsoft.com/kb/322756/ ) How to back up and restore the registry in Windows

   1. On the Exchange computer, log on by using the Exchange administrator account, and then start Registry Editor.
   2. Locate and then click the following registry subkey:
      HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\MSExchangeWeb\OWA
   3. On the Edit menu, point to New, and then click DWORD Value.
   4. Type DisableAttachments for the name of the DWORD value, and then press ENTER.
   5. Right-click the DisableAttachments DWORD value, and then click Modify.
   6. Under Base, click Decimal.
   7. In the Value data box, type one of the following numbers:
          * To permit all attachments, type 0.
          * To permit no attachments, type 1.
          * To permit attachments from back-end servers only, type 2.
   8. Click OK.
   9. Open a command prompt, type net stop w3svc, and then press ENTER.
  10. After the services stop, type net start w3svc, and then press ENTER.
