Microsoft Outlook 2002, included with Office XP, introduced new restrictions to stop possible unsafe e-mail attachments from being opened or saved. This tweak allows you to override those restrictions.

Open your registry and find the key below.

Create a new String value, or modify the existing value, called "Level1Remove" and set it to equal a semi-colon separated list of the extension you want to allow.

Restart Outlook for the change to take effect.

Note: Any files with the following extensions are normally prohibited from being opened or saved when received as e-mail attachments: "ade, adp, asx, bas, bat, chm, cmd, com, cpl, crt, exe, hlp, hta, inf, ins, isp, js, jse, lnk, mda, mdb, mde, mdz, msc, msi, msp, mst, pcd, pif, prf, reg, scf, scr, sct, shb, shs, url, vb, vbe, vbs, wsc, wsf, wsh"

		(Default)	REG_SZ	(value not set)
		Level1Remove	REG_SZ	"bat;exe;hlp"

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