Hi Using Exchange 2003 SP1. How can I restrict the handling of attachments in OWA. Currently I have disabled attachments as it only checks by file type extensions, and a user can change the file type name. I want to allow only certain attachment types like word doc or text. Can I use mime types to allow these types ? Where can I get a list of the various mime types ? Also is there any place that a full description and difference between the two levels of file types.
