Windows XP - Getting blocked attachments to work in Outlook

Outlook XP, which is part of the Office XP package, blocks certain e-mail attachments that may contain viruses. Unfortunately, this feature often proves to be a nuisance when you receive files from colleagues that are guaranteed to be virus-free.

Below you will find a list of all file extensions that have been blocked. Until now, you had to use tricks to get around this, for example by compressing the file as a ZIP, but this is not a compromise in the long term. To completely override this blockade, proceed as follows.

1. Click here to download a small registration file. Make a note of the path, open it and double-click on the file Outlook.reg.

2. After confirming twice, the values are entered in the Windows registry. Outlook now allows all attachments.

Manually block certain attachments

However, if you would like to block some attachments, you can do so from now on:

1. In the start menu, open Execute and enter in the command line regedit followed by Enter. This reveals the Windows Registry Editorwhich can be used in exactly the same way as Explorer.

2. Now scroll through the keys (folders) HKEY_CURRENT_USER\S oftware\Microsoft\Office\10.0\Outlook\Security and double-click on the value in the right-hand pane Level1Remove.

3. In the small window that appears there is a line that contains all authorized attachments.

4. To block a particular file type, simply select and delete it. The deleted file will then be blocked.

Here is the list with all File typeswhich are blocked:
