Outlook Blocking Attachments

By | 5 November, 2008

WARNING/Disclaimer :- this tip edits the registry of your computer.  Only do this if you are confident you know what your doing.

For Outlook 2000 (SP3), Outlook 2002, and Outlook 2003 an update to security means that some attachments are blocked for your own protection from the nasty people of the internet… but sometimes you actually want that attachment.  So if you want or need to stop Outlook blocking that nice .exe here’s how to change your registry settings (See the Warning at the Top!)

1. CLick Start > Run > Regedit {enter}

2. HKEY_CURRENT_USER\Software\Microsoft\Office\10.0\Outlook\Security

NOTE for Outlook 2000 (SP3) change the 10.0 for 9.0, and for Outlook 2003 change the 10.0 for 11.0)

3. Right click in the right Pane and select New > String Value.

4. Call the new string Level1Remove.

5. Now you need to tell the registry what you want to allow through, and you need to do it for EACH file extension you want to let through, for this example Im going to let through executable programs, and MS Access Databases.


6. Double click the Level1Remove string you just created.

NOTE You need to type every extension (preceeded by the full stop) and seperate each with a colon (no spaces)

7. When you are done click OK and close the registry editor.

If you’ve not just trashed your registry you will now be able to open previously blocked attachments.
