Stop Blocking Attachments in Outlook Express 6.

Outlook Express 6 can be configured to block any attachments whose extensions are in Internet Explorer 6's list of unsafe file types. (We've even seen new systems that had attachments blocked by default.) If such an attachment arrives, you'll get a message like "Outlook Express removed access to the following unsafe attachments in your mail:".

Specifically, OE 6 blocks attachments having any of these extensions: .asp, .bas, .bat, .chm, .cmd, .com, .exe, .hlp, .hta, .inf, .isp, .js, .jse, .lnk, .msi, .mst, .pcd, .pif, .reg, .scr, .url, .vbe, .vbs, .ws, and .wsh. You can't remove items from this list, as it's hard-coded in the file Shdocvw.dll. Other file types that have the box Confirm open after download checked in Windows Explorer's Edit File Type dialog may also be blocked.

To turn off this feature in Outlook Express, select Options from the Tools menu, click on the Security tab, and uncheck the box that says Do not allow attachments to be saved or opened that could potentially be a virus. Once you click on OK, you should also be able to open attachments that arrived while this feature was on.
