After installing Symantec Enterprise Vault, users receive “Invalid conversion id 64-0x0” error when viewing attachments

SUMMARY

When viewing attachments by clicking on the binocular icon, or by using the Rich or Text View in the AttachView context menu, users receive the following error

Invalid conversion id 64-0x0

CAUSE

This issue typically occurs when AttachView is installed on a front-end server where an archiving solution such as Symantec Enterprise Vault is installed. Certain archiving solutions enable the WinHTTP proxy. By default, the front-end server is not included in the WinHTTP bypass list.

RESOLUTION

To correct this issue, add the front-end server where Messageware is installed, to the WinHTTP bypass list using the proxycfg command.

Before running this command make a backup of the registry key where this information is kept by exporting this key to a REG file. This file can be restored should it be required at a future date

The steps outlined below indicate how to export the registry key and add the front-end server to the Bypass List.

 

  1. Exporting the registry information
    1. Open the registry editor and navigate to: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Internet Settings\Connections\
    2. Click on the File\Export (Windows 2003) or click on Registry\Export Registry File (Windows 2000)
    3. Enter a file name and take the default (*.reg) as file type
    4. Click on the Save button
  2. Add the server to the WinHTTP bypass list
    1. From the command line enter the following command and press enter
      proxycfg -p <ServerName> "IPAddress"
      (Where <ServerName> is the server you are adding to the bypass list and IpAddress is the IP address of the server you’re adding to the Bypass List)
    2. Clear the local browser cache (Tools\Internet Options\Delete Files) and refresh the page
  3. Verify that users are able to view attachments in OWA

 

A different parameter may be needed to configure the Bypass List, or to configure direct access to the WinHTTP proxy. Refer to the parameter list detailed in the Microsoft documentation Proxy Configuration Tool for more information. You can refer to the link below for more information:

MORE INFORMATION

 

Should this behaviour occur after Symantec Enterprise Vault was removed, refer to the Messageware knowledgebase article below

According to Microsoft, after using the proxy configuration tool, the original proxy settings cannot be restored; hence we strongly recommend making a backup of the registry. Please refer to the link below for more information:
