Outlook has blocked access to unsafe attachments

Outlook assumes that users aren’t smart enough to be allowed access to executable file types. This assumption may or may not be valid, depending on your user base.

Microsoft has a writeup with an explanation, but the basic idea is pretty straightforward. Also available is the list of attachments blocked in Outlook 2007.

If you’ve decided your users should have access to certain restricted file types, the process is actually very simple; just a quick registry edit and you’re on your way.

  1. Start…Run…”regedit”
  2. Go to HKEY_CURRENT_USER\Software\Microsoft\Office\11.0\Outlook\Security
  3. Create a new string value called Level1Remove
  4. Enter in the file extensions you want to use, such as .exe or .bat
  5. You can have multiple file types separated by a semicolon like this: “.exe;.com”

This applies to Outlook whether or not you use Outlook Connector.

Create a mailing list of Outlook Connector users

I once had a request to populate a mailing list with Outlook Connector users.  Below is the script that was born.

The script assumes a hardcoded listname of “OCusers@example.com”, use Notepad to search and replace OCusers@example.com with the correct list name.

Also, you need to manually create the list in MDaemon first, otherwise the script will fail.  Lastly, be aware that you cannot manually add users to the list, the entire membership list is wiped and replaced each time the script runs.  The intention is to run the script automatically on a schedule to keep the list up to date.

@ECHO OFF
CD C:\MDaemon\App
IF NOT EXIST GroupWareUsers.dat goto ERROR
IF NOT EXIST OCusers@example.com.grp goto ERROR
COPY OCusers@example.com.grp OCusers@example.com.bak
FIND “;” < OCusers@example.com.bak > OCusers@example.com.grp
FIND “@” < GroupWareUsers.Dat >> OCusers@example.com.grp
GOTO END
:ERROR
ECHO Could not find needed file, check and make sure GroupWareUsers.dat and OCusers@example.com.grp exist
:END
