Outlook 2000, XP and 2003 have a 'feature' that blocks attachments based on the file extension. This is great for blocking viruses, but unfortunately, it also blocks legitimate attachments from coming into your Inbox.
DetachOL gives you total control of your attachment types.
Use DetachOL to change which file types are blocked, according to YOUR needs, not those of the Outlook development team!

DetachOL has a new 'Wizard' based interface, to make your choices easier. You can select 'Expert' features (as seen in DetachXP) by choosing the 'Custom' selection in the program.
