There are, generally, two ways of working with Outlook attachments.

1) The "official", Microsoft way is to edit the registry to permit the attachment types you want to allow.


2) There are third-party programs that allow for the easy switching of permissions for Outlook attachments.


TweakOL is one I've found works well; DetachOL is also a good standalone app., while Attachment Options is an interesting plugin to the Outlook control panel.

Microsoft Outlook, since outlook 2000 SR1, does not let you send certain attachments either, while an attachment icon will be seen by the recieve, outlook has actually stripped the attachment before you sent it to them.
Denied file extensions:
.ade, .adp, .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, .reg, .scr, .sct, .shs, .url, .vb, .vbe, .vbs, .wsc, .wsf or .wsh

Ever since oulook 2000 sr1, they have denied these attachments by default. Send a .zip or .txt file- or add these extenstions to your file name like
file.bat.zip  or  file.exe.txt  and have the recipant remove the added extension

There are many systems that remove .exe or .bat (and the others listed) so the renaming is a very good way to assure that the files reach the intended target. Hotmail will not accept, or send the above attachments, and lot's of virus scanners for email servers also remove them, even if they are clean, I've seen this 100 times. It's the better safe than sorry routine.
