This document describes the issue where Outlook does not create a VoiceMessage.wav file. When you attempt to play a voice message in Outlook, a copy of that message is placed in a temporary folder. Windows increments the name up to 99. This is not a specific process used just for Cisco Unity Connection messages. Any application that uses the same name for each attachment experiences this issue.


At times, when you attempt to play a voice message in Outlook, you might receive this error:

Cannot create file: VoiceMessage.wav. Right-click the folder you 
want to create the file in, and then click Properties on the
shortcut menu to check your permissions for the folder.


Complete these steps in order to address the issue:

  1. In order to locate the folder where the files are stored, look in the registry for the path based on your version of Outlook:
    • Outlook 2003 - HKEY_CURRENT_USER\Software\Microsoft\Office\11.0\Outlook\Security
    • Outlook 2007 - HKEY_CURRENT_USER\Software\Microsoft\Office\12.0\Outlook\Security
    • Outlook 2010 - HKEY_CURRENT_USER\Software\Microsoft\Office\14.0\Outlook\Security
    • Outlook 2013 - HKEY_CURRENT_USER\Software\Microsoft\Office\15.0\Outlook\Security
  2. Find the OutlookSecureTempFolder string value and make a note of the path found in value data field.

    The location is similar to:

    C:\User\[user]\AppData\Local\Microsoft\Windows\Temporary Internet Files\
  3. Once you have the location from the previous step, use Explorer to navigate to the folder location.
  4. Delete the files in the folder that start with VoiceMessage.
