This patch is intended for users with MS Outlook 2000/98 and Service Pack 1 & 2, which includes a 'security feature' blocking all incoming attachments with the extensions like .exe and .lnk. The patch will update the outllib.dll in your office folder and disable the security features on specific extensions. The original outllib.dll will be copied to the subdirectory 'Outlook 2000 Security Patch' in your system folder. Close Outlook before patching! Usage at your own risk!.
