How to edit e-mail security attachment file type list

Følgende forklaring findes i Outlook.

Attachment file types blocked by Outlook
There are two levels of attachment security. Access to level 1 files is blocked and can't be changed. When you receive an attachment with a level 2 file type, you will be prompted to save the file to your hard disk. If you use Microsoft Exchange Server, your administrator can add and remove file types for both levels of e-mail security. If a file type is added to both levels, it will be treated as a level 1 file type.

Ok, så takker jeg for point:)
