How to unblock Access attachments in Outlook 2007

 

Question:  How can I unblock Access attachments within Outlook 2007?

Outlook 2007, Outlook 2003, Outlook 2002 and Outlook 2000 SP3 (but not Outlook 98 or earlier Outlook 2000 versions) allow the user to use a registry key to open up access to blocked attachments. (Always make a backup before editing the registry.) To use this key:

  1. Run Regedit, and go to this key:

    HKEY_CURRENT_USER\Software\Microsoft\Office\10.0\Outlook\Security (change 10.0 to 9.0 for Outlook 2000 SP3 or to 11.0 for Outlook 2003, 12.0 for Outlook 2007 )
  2. Under that key, add a new string value named Level1Remove.
  3. For the value for Level1Remove, enter a semicolon-delimited list of file extensions. For example, entering this:

    .mdb;.accdb

    would unblock Microsoft Access files of various versions. Note that the use of a leading dot was not previously required, however, new security patches may require it. If you are using  "mdb;accdb" format and extensions are blocked, add a dot to each extension. Note also that there is not a space between extensions.
  4. Outlook may need to be closed and reopened for the attachment to be unblocked.

To force users to save *.zip files to the hard drive before opening, add .zip to the extensions step 3.

After applying this registry fix or using one of the tools, the user still has to save the attached file to a system drive before opening it. In effect, the fix rolls the attachment behavior back to Outlook 2000 SR-1, with its included Attachment Security Fix. An end-user cannot bypass this "save to disk" behavior and open the file directly from the mail message, though an Exchange administrator can.
